Abstract Submission Information

Contents

Rules and Regulations

    • Presenter must be listed as first author on the paper at the time of submission.
    • The presenting author must be the one to make the submission.
    • Presenting/first author of each abstract must register for the meeting by the regular registration deadline.
    • Abstracts may not be presented by proxy.
    • All abstracts must be submitted through the abstract submission system.

AAS Members

    • Any AAS member may submit an abstract.
    • Educator Affiliates may only submit education-related abstracts.
    • Suspended/inactive members must reinstate their membership.

Nonmembers

    • Nonmembers may present only once every 10 years.
    • Each nonmember submitter is required to have a sponsor who is an active AAS Full Member; the sponsor will be notified via email, but no action is required on their part unless they have a concern about the sponsorship.
    • Undergraduate students pursuing an astronomy or physics degree are encouraged to become Undergraduate Student Members of the Society and submit their abstracts with a Full Member sponsor. Undergraduate nonmembers must submit their abstracts as nonmembers and are subject to the usual rules governing presentation of abstracts by nonmembers. Society of Physics Students (SPS) affiliates of the AAS are considered nonmembers for abstract submission but may register for the meeting at the Undergraduate Student Member rate.
    • AAS Educator Affiliates are considered nonmembers for scientific research abstracts.

Abstracts Per Meeting

Regular Submissions: You may submit the following Regular abstracts per meeting:

    • One Research abstract (oral, poster, iPoster or iPoster-Plus) or Dissertation abstract (oral)
    • Up to two History abstracts (oral, poster, and/or iPoster)
    • Up to two Education abstracts (oral, poster, and/or iPoster)

In addition, you may be invited to give an oral presentation in one of the following types of sessions:

    • Plenary Session (prize or invited talk)
    • Special Session (summer and winter), Division Meetings or Meeting-in-a-Meeting (summer only)

Abstracts for invited presentations in Plenary, Special Sessions, Division Meetings, or Meeting-in-a-Meeting sessions do not count against your allotment of Regular abstracts as stated above.

In addition, you may submit a Regular Research Contributed abstract (oral or poster) to a Special Session or Meeting-in-a-Meeting session that is accepting contributed oral and/or poster presentations. This abstract does not count against your allotment of Regular abstracts, but acceptance is subject to approval by the session organizer. If your oral  or poster presentation is not accepted into the requested Special Session, Divison Meeting or Meeting-in-a-Meeting, it will be scheduled in an ordinary oral or poster session unless doing so would cause you to exceed the number of abstracts permitted per meeting as described above.

Late Submissions: If you have not submitted any Regular abstracts of any type listed above, you may submit one Late poster abstract.

There is no limit to the number of Regular or Late abstracts that you may co-author.

Deadlines

We will strictly adhere to the following deadlines:

    • Regular Abstract Deadline: 2 April 2019 — Abstracts received after this deadline will be considered Late abstracts. There are NO exceptions to this rule.
    • Late Abstract Deadline: 1 May 2019 — poster abstracts only.

Edits to Abstracts

    • If you have a problem with the scheduling of your presentation, please email the abstract help desk. We will try to accommodate your request if possible. No changes will be made to the schedule after 1 May 2019.
    • We understand that edits sometimes need to be made to abstracts after they are submitted. We try hard to accommodate edits and changes as we lead up to the conference, but due to certain publishing deadlines we will be unable to edit abstracts within four weeks of the meeting start date.

Types of Presentations

Plenary Presentations

    • Prize Lectures
    • Invited Lectures

Plenary sessions are 50 minutes long; no other sessions or events are scheduled in parallel with them. To allow time for introductions, prize presentations, and question-and-answer (Q&A) periods, prize and invited lecturers should plan to speak for at most 40 minutes. Plenary speakers will receive special abstract and presentation instructions from the AAS Executive Office.

Research Presentations

    • Research Oral
    • Research iPoster
    • Research iPoster-Plus
    • Research Poster
    • Dissertation Oral

History Presentations

    • History Oral
    • History iPoster
    • History iPoster-Plus
    • History Poster

Education Presentations

    • Education Oral
    • Education iPoster
    • Education iPoster-Plus
    • Education Poster

The foregoing three categories are collectively referred to as Contributed presentations. To learn more about the four available presentation formats, see the following short YouTube videos:

Research, History, and Education oral presentations, as well as Dissertation oral presentations, are arranged by topic and are scheduled in 90-minute sessions of five to nine talks each. For a Research, History, or Education oral presentation, allow minutes for the talk, 3 minutes for questions, and 2 minutes for speaker transitions. For a Dissertation oral presentation, allow 15 minutes for the talk, 3 minutes for questions, and 2 minutes for speaker transitions.

Research, History, and Education posters allow far more time and flexibility than the corresponding oral presentations and are the default presentation types. Posters are arranged by topic and are usually displayed for one full day, including up to 2 hours when very few other sessions or events are scheduled, though if circumstances permit, at some meetings posters are displayed for multiple days.

Other Presentations

    • Division Prize & Invited Talks
    • Division Contributed Orals & Posters
    • Special Session Invited Talks
    • Special Session Contributed Orals & Posters

When AAS Divisions meet with the AAS, they organize oral and poster sessions and, sometimes, prize and/or invited lectures. The latter are sometimes scheduled into parallel oral sessions and may have time limits different from those associated with plenary presentations or short oral presentations. Division prize and invited lecturers will receive special abstract and presentation instructions from the AAS Executive Office or their respective Division leaders.

The format of Special Sessions is at the discretion of the organizer, who may choose to include invited presentations and/or short oral and/or poster presentations. Invited lecturers will receive special abstract and presentation instructions from the AAS Executive Office or their respective session organizers. If contributed presentations are welcome, suitable categories will be included on the abstract-submission form. Acceptance of such abstracts is at the discretion of the relevant session organizer, but if a paper is not accepted into the requested Special Session, it may be scheduled in another appropriate session of contributed presentations. If enough poster abstracts are received, an associated poster session will be scheduled on the same day(s) as the Special Session.

Submission Process

Abstracts must be submitted through the presenting author's AAS record. Co-authors are not eligible to substitute as the presenting author. The presenting author will be notified once the schedule has been determined.

Abstract Form Details

The form contains instructions on the various steps required to complete a submission. Once you have completed the Title Step you are assigned a control number and may exit and re-enter the system.

    • The abstract must be complete and submitted by the deadline, 9:00 pm Eastern time, 2 April 2019.
    • The abstract body text can be a maximum of 2,250 characters (which includes letters, numbers, punctuation, spacing, returns, and symbols/special characters).
    • To enter co-authors, you must have the following: full first and last name, e-mail address, and affiliation.
    • You can continue to make changes to your abstract before the deadline. To edit an abstract, click the "Return to Draft" button. This will return the abstract to draft status, allowing you to make further edits to the abstract. Please remember to resubmit the abstract before the deadline.

To switch the presenting author to a co-author you must submit a new abstract by logging in as the new presenting author.

Topical Categories

Categories are used as a guide for the AAS Vice-Presidents to build coherent sessions. The final session assignments and session titles are at the discretion of the Committee.

Presentation Guidelines and Tips

Poster Presentations

If you're interested in printing your poster near the meeting venue, try the FedEx Office Print & Ship Center (3112 S Grand Blvd, St Louis, Missouri 63118). Contact them at usa4701@fedex.com if you have any questions.

Guidelines

Posters allow far more time and flexibility than short talks and are the default presentation type. Posters are ideal for using charts, graphs, or detailed visual aids. The poster area serves as the meeting's social center.

    • Your poster must fit within the 44" x 44" display area provided.
    • Posters are sorted by topic.
    • Up to two hours each day will be set aside for poster presentations when no other sessions are scheduled. Authors should be present at their posters during those hours.
    • Posters may be set up starting at 6:30 pm on Sunday. Posters will remain up through Wednesday.
    • Posters must be removed by the close of the exhibit hall at 6:30 pm on Wednesday. Posters left up after this time will be recycled.
    • Poster presenters are encouraged to be at their posters during the early morning, morning and evening poster sessions on the day of their presentation.

Tips

    • When preparing your poster, remember to use bold graphs, photographs, figures, and tables. Include a title and the names of authors in large type. Text should be large enough (at least 20 points) to be legible from a distance of three to four feet. Keep the poster simple and easy to read.
    • There is a good article on preparing an eye-catching poster at naturejobs.com, Presentations: Billboard Science.
    • Consider posting a photo of yourself with your presentation, along with contact information (including your cell number if you want people to be able to reach you during the meeting).

iPoster Presentations

Guidelines

With the iPoster system, you will be able to create an interactive presentation that includes high-resolution images, high-definition videos, narration, interviews, viewer surveys, and more.

    • iPosters are created online using easy-to-use, web-based templates.
    • After sorting is complete, authors will receive login credentials to create their iPosters.
    • Your iPoster will be displayed at the meeting on large-format HD touch screens and will be downloadable to smartphones, tablets, and desktop computers during the meeting and available on an iPoster portal afterward.
    • You can add as much text and media content as you need to present your research with all the detail it deserves.
    • iPosters will be limited to 140 available spots on a first-come, first-served basis.
    • iPoster presenters will stand at their own touch screen for the hour of the poster session. We are currently considering an early morning poster-viewing session before the first plenary talk, and this would be additional available time.
    • iPoster screens are available at all other times to display the iPosters in the gallery.
    • iPoster sessions will be in conjunction with regular poster sessions — submitters must choose a regular poster or an iPoster, not both.

Tips

    • Viewers can reach out to you via the "Contact Author" button at the bottom of your iPoster.
    • Include narration so attendees can listen to your presentation (while they scroll through your iPoster) even when you're not there.

Student Award Poster Presentations

Please read the Chambliss Astronomy Achievement Student Award Rules for eligibility requirements.

Oral Presentations

Guidelines

To avoid too many oral sessions running simultaneously, the number of oral presentation time slots is limited. Oral presentations may be changed to posters if there are no remaining slots. All authors whose abstracts are changed will be notified.

    • Five minutes are allowed for the oral presentation and three minutes for open discussion/Q&A.

Tips

    • When preparing your presentation, we suggest a maximum of three slides for a five-minute talk. Slides should be uncluttered and easy to read.
    • Practice a few times so the presentation fits comfortably into the five-minute slot.
    • Read the AV instructions.
    • Read “Speak Your Science: How to Give a Better Conference Talk” by Emily Lakdawalla for advice on giving a science talk of any length.

Dissertation Presentations

If you would like to present a Dissertation talk, select the Research Contributed/Dissertation abstract form.

    • Dissertation presentations are 15-minute talks plus 5 minutes for discussion/Q&A. They should be based upon the author's dissertation research and will be presented within parallel oral sessions of appropriate topics.
    • Only students or graduates within one year of having a doctorate conferred by their university or college are eligible. "One year" is measured from the regular abstract deadline, not the date of the meeting itself. The author's advisor must attest to this eligibility in writing. The author must submit a copy of the thesis advisor's letter in PDF format through the abstract-submission website by the regular deadline. A PDF copy of an email message is sufficient as long as the advisor's email address is legible. If the advisor letter is not received, the dissertation abstract will automatically be treated as an ordinary oral abstract.
    • Students or graduates wishing to submit Dissertation abstracts must be accepted for membership in the AAS by the abstract deadline. (The membership form can be downloaded from the Membership section of the website or obtained from the AAS Executive Office.)
    • These abstracts are subject to the same rules of preparation and submission as regular abstracts, but they will be specially marked with a “D” in the program materials.
    • Winter meeting only: If you would like to be considered for the Rodger Doxsey Travel Prize, please review the background and rules for submission.

Publication of Abstracts

The meeting and abstract schedule are published in various formats:

    • Paper Final Program — Distributed at the meeting if you opt in during registration.
    • Astrophysics Data System (ADS) — Abstracts are sent to ADS and typically published two weeks prior to the meeting.
    • Mobile App — Our "Meetings by AAS" mobile app puts the entire conference program in your pocket and ensures that it's always up to date. The AAS 234 meeting guide will be available a week or two before the meeting begins.
