Every presentation at the AAS summer and winter meetings is accompanied by an abstract no more than 2,250 characters long that describes the research being presented. Meeting attendees wishing to present — whether via a talk or a poster — must submit a proposed abstract by the set abstract deadlines.

Abstract Login Instructions

To submit an abstract, you must first log in to the system using your AAS login credentials.

• If you are a member of the AAS you should already have a login. 
• If you are not a member of the AAS you may create an AAS login if you do not already have one.

If you are an undergraduate student member, inactive member, pending member, or nonmember of the AAS you will need to select a sponsor (a sponsor is an active AAS Full Member; the sponsor will be notified by email, but no action is required on their part) during the submission process to finalize submitting your abstract to the system.

Making Changes after the Submission Deadline

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.

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.
