Mapping stellar surfaces III: An Efficient, Scalable, and Open-Source Doppler Imaging Model

rodluger/showyourwork 12 Oct 2021

It is also critical to the detection and characterization of extrasolar planets, in particular those targeted in extreme precision radial velocity (EPRV) searches, which must contend with stellar variability that is often orders of magnitude stronger than the planetary signal.
