Research Assistant Professor
Dr. Aaron Geller studies how stars and planets are born and how they change with time, both through observations and numerical simulations. In particular, he is interested in how gravitational interactions between stars and planets in star clusters shape the stellar and (exo)planetary systems that we observe. He also focusses on strange, exotic stars that don’t conform to our standard understanding of stellar evolution, and compact objects like black holes and neutron stars. In addition, Dr. Geller develops visualizations of his and others’ work for both research and outreach purposes, and for use at Northwestern, the Adler Planetarium, within classroom lessons, and for the general astronomy enthusiast.
