About Division of Astrophysics

The Division of Astrophysics (DAP), organized in 1970, engages in observational and theoretical investigation that relates to the study of physical processes in stars and other discrete galactic sources, galactic structure and evolution, the early history and evolution of the Universe, and the Sun and solar activity. Division interests also have significant overlap with other APS divisions such as Particles and Fields, Nuclear Physics, and Plasma Physics.

History of DAP

From 1970 to 1983, the Division of Astrophysics was called the Division of Cosmic Physics. Divisions of the Society is a brief history of the APS divisions and listing of executive officers from those divisions.

Join APS Sections and Topical Groups

We urge all of our division members to consider joining sections, forums and topical groups relevant to you. Membership is free for sections and forums, and very inexpensive for topical groups. There are benefits beyond the obvious ones of the meetings, newsletters, and lobbying efforts of the units. Your membership benefits the units and, indirectly, astrophysics.

The geographical sections are funded entirely by APS in proportion to the number of members. It takes seconds to register for free online and help your section. The topical groups (e.g., Plasma Astrophysics, and Gravitation) are funded through their dues, but are awarded invited sessions at APS meetings and APS Fellowship Nominations in proportion their membership. More members in groups of interest to you result in more talks and more Fellows in your area. Further, the existence of the topical groups depends on their maintaining a membership threshold. There are several good reasons to join, and no good reasons not to.
