Capt'n General: A generalized stellar dark matter capture and heat transport code

Abstract

Capt'n General is a FORTRAN90 standalone package that can be used to compute the capture and heat transport of dark matter in stars. It can compute capture rates for constant, velocity and momentum-dependent DM-nucleon elastic scattering cross sections, as well as non-relativistic effective operator interactions. Capt'n General can be interfaced with the GAMBIT global fitting codebase as well as stellar evolution simulation codes such as MESA.
