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.

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 5 minutes for the talk, 3 minutes for Q&A and 2 minutes for change over. For a dissertation oral presentation, allow 15 minutes for the talk, 3 minutes for Q&A and 2 minutes for change over.
Regular, history, and education iPosters allow far more time and flexibility than the corresponding oral presentations and are the default presentation types. iPosters are arranged by topic and 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 at least one year 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. iPoster presenters will stand at their own touch screen for an assigned hour of the iPoster session. iPoster screens are available at all other times to display the iPosters in the gallery and sessions will be scheduled during the morning iPoster session and the afternoon iPoster session. The first author must be present at their assigned terminal during their scheduled session.

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 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 abstracts are received, an associated poster session will be scheduled on the same day(s) as the Special Session.
