Abstracts Per Meeting
You may submit the following Regular abstracts per meeting:
- One Research Contributed abstract (oral or iPoster/poster) or Dissertation abstract (oral)
- Up to two History abstracts (oral and/or iPoster/poster)
- Up to two Education abstracts (oral and/or iPoster/poster)
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) or Meeting-in-a-Meeting (summer only)
Abstracts for invited presentations in Plenary, Special, or Meeting-in-a-Meeting sessions do not count against your allotment of Regular abstracts.
In addition, you may submit a Regular Research Contributed abstract (oral or iPoster/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 iPoster/poster presentation is not accepted into the requested Special Session or Meeting-in-a-Meeting, it will be scheduled in a regular oral or iPoster/poster session unless doing so would cause you to exceed the number of abstracts permitted per meeting as described above.
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.
We will strictly adhere to the following deadlines:
- Regular Abstract Deadline: 3 October 2018 - Abstracts received after this deadline will be considered late abstracts. There are NO exceptions to this rule.
- Late Abstract Deadline: 5 December 2018 - 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 8 December 2018.
- 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.
- 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 Contributed Oral Presentations
- Research Contributed iPoster/Poster Presentations
- Dissertation Oral Presentations
- History Oral Presentations
- History iPoster/Poster Presentations
- Education Oral Presentations
- Education iPoster/Poster Presentations
Regular, 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 regular, history, or education oral presentation, allow five minutes for the talk and three minutes for Q&A. For a dissertation oral presentation, allow 15 minutes for the talk and 5 minutes for Q&A.
Regular, 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 about 90 minutes when very few other sessions or events are scheduled, though if circumstances permit, at some meetings they are displayed for multiple days.
- Division Prize & Invited Presentations
- Division Contributed Oral and Poster Presentations
- Special Session Invited Presentations
- Special Session Contribted Oral and Poster Presentations
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 regular oral sessions and may have time limits different from those associated with plenary presentations or contributed 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 sessions is at the discretion of the organizer, who may choose to include invited presentations and/or contributed 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 will 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.
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, 3 October 2018.
- 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.
Categories are used as a guide for the Scientific Organizing Committee to build coherent sessions. The final session assignments and session titles are at the discretion of the Committee.

Posters allow far more time and flexibility 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" area.
- Poster abstracts are sorted by topic.
- Approximately one hour each day will be set aside for poster presentations when no other sessions are scheduled. The authors should be present at their poster during that time.
- Posters may be set up starting at 8:00 am on Tuesday-Thursday and removed daily at 6:30 pm. Friday late posters can be set up starting at 8:00 am and taken down by 4:00 pm. Posters must be removed by the close of the exhibit hall at 4:00 pm on Friday. Posters left up after this time will be recycled.
- Poster presenters are encouraged to be at their poster during the AM coffee break and the evening poster session on the day of their presentation.
- 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 to be legible from a distance of three to four feet, ~ 20 point font. 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.
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.
- 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 for six months after it concludes.
- 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.
- iPoster screens are available at all other times to display the iPosters in the gallery.
- iPoster sessions will be in conjunction with regular poster session — submitters must choose a regular poster or an iPoster.
- Viewers can reach out to you via the "Contact Author" button at the bottom of your poster.
- 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.
To avoid too many oral sessions running simultaneously, the number of oral presentation time slots is limited. Oral presentations can 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 normal oral presentation and three minutes for open discussion.
- 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.
If you would like to present a dissertation abstract, select the Research Contributed/Dissertation abstract form.
- Dissertation Abstracts are 15 minutes oral presentations plus 5 minutes for discussion. They should be based upon the author’s dissertation material, and will be presented within regular oral sessions of appropriate topics.
- Only students or graduates within one year of having a PhD conferred by their university or college are eligible. The "one year" is measured from the regular abstract deadline date, not the date of the meeting itself. The author’s advisor must attest to this fact in writing. The author must submit a copy of the thesis advisor’s letter in PDF format through the abstract submission website by the abstract 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 will automatically be treated as a regular 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.
The meeting and abstract schedule are published in various formats:
- Paper Final Program – Distributed at the meeting; includes abstract titles.
- Online PDF of Abstracts – Available two weeks prior to the meeting; includes full abstract text.
- Astrophysics Data System (ADS) – Abstracts are sent to ADS and typically published two week prior to the meeting.
