Modeling the Impact of Starspot Inhomogeneity on Spectroscopic Retrievals of Directly-Imaged Planets

Alex R. Howe, Natasha Latouf, Christopher C. Stark +2

The paper models how starspot inhomogeneity on host stars can affect spectroscopic retrievals of directly imaged Earth‑like exoplanets, finding that Sun‑like activity has little im…
