Content of AAS Meetings


At the semi-annual meetings of the AAS there are five basic types of presentation sessions (described in detail below). Four are planned one meeting in advance by the AAS Committee on Meetings and one is composed of Member contributions.

The Committee on Meetings is composed of the three Vice-Presidents, the Executive Officer (or designee) and the President (ex-officio). The chair of the Committee on Meetings is always the senior Vice-President.

Types of Sessions at AAS Meetings

During Winter Meetings, posters are displayed for one day and late abstracts are usually displayed on the final day of the meeting. During Summer Meetings posters are displayed for two days. Monday poster sessions continue on Tuesday and Wednesday poster sessions continue on Thursday.

Contributed Sessions

Contributions may be either oral or poster (both types are referred to individually as "papers"). All Members may contribute presentations, which are sorted and grouped by a committee of volunteers shortly after the abstract deadline for each meeting.

Further rules governing the submission of contributed papers, including proper submission guidelines and deadlines are published in the preliminary announcement for each meeting, which is sent in print form to each AAS Member and also appears on the AAS web pages approximately two months before the actual meeting date.

Invited Speaker Sessions

Invited Speakers are chosen by the Committee on Meetings.

Members may communicate ideas for possible invited speakers directly to the Committee on Meetings by sending a short proposal describing the individual(s), their potential topic for presentation and some explanation of why they should be invited to speak at the meeting.

These short proposals should be sent via email to Kevin Marvel by 15 May (for Winter Meetings) or 30 September (for Summer Meetings).

Special Sessions

Town Hall Meetings

Town Halls are intended for federal agencies and national observatories to present policy information and to solicit feedback from their user communities. Current missions and facilities should request Special Sessions (see above) to present results. Future missions and facilities can utilize exhibits, workshops or splinter meetings (see below), or websites to provide information to the community.


Splinter Meetings

  • Splinter meetings are held at Winter and Summer meetings.
  • Splinter meetings can be scheduled before, during or after AAS conference days (additional fees may apply to meetings scheduled after the AAS meeting closes).
  • Any AAS member can request a Splinter meeting; participants must be registered for the current meeting.
  • A summary of the meeting topic and content must be submitted.
  • Public Splinter meetings should not typically conflict with AAS scheduled Invited Talks.
  • Private (invitation only) Splinter meetings can be scheduled at any time.
  • The identified session organizer must be an AAS Member and should submit complete contact information including onsite contact information.
  • Events can be published online or in the program update with the approval of the AAS Executive Office.
  • Costs associated with catering and equipment rental are the responsibility of the splinter meeting organizer. The fees will be invoiced by the AAS once the meeting closes and is audited.
  • Meeting requests are honored and assigned on a first come, first served basis depending on meeting room availability.
  • Meeting organizers will be notified via email of specific room assignments by 15 December for Winter Meetings and 15 May for Summer Meetings.
  • All requests submitted after the deadline will be assigned based upon availability and will not be included in the printed meeting program.
