Circular polarization signals of cloudy (exo) planets

L Rossi, DM Stam - Astronomy & Astrophysics, 2018 - aanda.org
Context. The circular polarization of light that planets reflect is often neglected because it is
very small compared to the linear polarization. It could, however, provide information on a …
