Stefan Arseneau

Astrophysicist

I am a stellar astrophysicist at the Center for Astrophysical Research at Boston University. I work on observational measurements of the core compositions of white dwarfs as part of buwd. Specifically, my work uses white dwarfs in wide binaries with main sequence stars to measure the gravitational redshifts of individual white dwarfs. I'm also interested in computational methods for astronomy, stellar pulsations, and the intersection of physics and machine learning methods.

Software I've helped develop:

  • corv: a tool for measuring radial velocities of DA white dwarfs
  • wdphoto: a tool for measuring radii of DA white dwarfs
  • spectromancer.py: a tool for managing MAGE observations of DA white dwarfs
