Aster G. Taylor

University of Michigan, University of Chicago


I am a graduate student in Astronomy at the University of Michigan, working with Fred Adams. I obtained my undergraduate degree in Astrophysics from the University of Chicago in 2023, where I worked primarily with Darryl Seligman.

I am a Fannie and John Hertz Fellow, a recipient of the Rackham Science Award, and a Michigan Institute for Computational Discovery and Engineering Fellow.

I primarily study theoretical and computational planetary science and astrophysics. Currently, I am working on the dynamics and accelerations of solar system small bodies, specifically on the origins of the mysterious accelerations of “dark comets”. I am also working on the radiative signatures of circumplanetary disks during giant planet formation. I am generally interested in fluid dynamics, minor bodies, planet formation, and plasma physics.

In my spare time, I like to hike, read science fiction (especially Ada Palmer and Iain Banks), play board games and Dungeons and Dragons, work out, and practice martial arts (Shaolin kempo and mixed martial arts).

I am also a citizen of the Muscogee (Creek) Nation of Oklahoma.

Please contact me at for questions and collaborations.
