Abstracts Per Meeting

You may submit the following Regular abstracts per meeting:

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

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

• Special Session or Meeting-in-a-Meeting

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-Plus) to a Special Session or Meeting-in-a-Meeting session that is accepting contributed oral and/or iPoster-Plus 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-Plus presentation is not accepted into the requested Special Session or Meeting-in-a-Meeting, it will be scheduled in a regular oral or iPoster-Plus 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 iPoster-Plus abstract.

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

Plenary Presentations

• 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.

Other Presentations

• Special Session invited presentations
• Special Session contributed 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 and Meeting-in-a-Meetings are at the discretion of the organizer, who may choose to include invited presentations and/or contributed oral and/or iPoster-plus 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 iPoster-plus 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.

Oral Presentations (in-person attendees ONLY)

Video Tutorial

Guidelines

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.

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.

Dissertation Presentations (in-person attendees ONLY)

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

• Dissertation Abstracts are 15 minutes oral presentations plus 3 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:

• Online Abstracts — Available prior to the meeting; includes full abstract text.
• Astrophysics Data System (ADS) — Abstracts are sent to ADS and typically published two weeks prior to the meeting.
