Call for Papers

We are happy to announce the Call for Papers for #AAS20 are now live through October 31, 11:59 p.m. PST! Don’t wait to submit!


  • AAS is using a new abstract management system to integrate with the new AAS database.
  • In order to submit an abstract or be included as a co-author ALL presenters and co-authors/co-presenters must have a profile, including a bio, set up in the AAS database.
  • You are encouraged to attend to this requirement as soon as possible. It is the responsibility of each author and co- author to create a profile and bio.
  • Those with existing profiles will need to add a bio in their profile even if they have previously uploaded a bio or CV.
  • DO NOT submit your abstract until all co-authors have been added, as you will not be able to add them afterwards.
