The Rodger Doxsey Travel Prize provides graduate students or postdocs within one year of receiving or receipt of their PhD a monetary prize to enable the oral presentation of their dissertation research at a winter meeting of the AAS. Other than the Doxsey prize the the AAS does not have funds to support travel by members or nonmembers to its meetings. The AAS International Travel Grant Program only provides support for US based astronomers to travel to meetings held outside the US.
AAS meetings are dynamic gatherings of professional astronomers from around the world. The winter meetings typically boast 2000 participants or more. The four days are filled with scientific sessions, both poster and oral as well as invited sessions from prominent researchers with exciting results. The summer meetings have topical sessions, which are more lengthy oral sessions focused on particular topics. The meeting program is decided upon by the three vice-Presidents with logistical details provided by the AAS meeting coordinator.
Currently the winter meeting location rotates between four cities, Washington, D.C.; Austin, Texas; Seattle, Washington; and Long Beach, California. Summer meetings are held in a variety of locations, which are chosen by the Council in response to proposals from interested institutions.
