Abstracts & Proposals

Seattle, Washington
241st meeting of the American Astronomical Society
Seattle, Washington
8 – 12 January 2023

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 Submission Is Closed

We are no longer accepting late abstracts. We have reached capacity for iPosters.

Note: The AAS is pleased to announce a new abstract category for this meeting entitled “Community & Profession”. This category encompasses content related to the professional astronomy community generally, including diversity, equity, and inclusion and related topics. Community & Profession abstracts can be submitted as Research Contributed presentations (category #54) or Education Contributed presentations. Note that the Rules & Regulations governing the number of abstracts an attendee may present have been updated as well.

We will strictly adhere to the following deadlines and scheduling:

  • 11 Oct: Regular abstract deadline

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.
