The Thermal Phase Curves of Proxima b

3-D climate simulations for the detectability of Proxima Centauri b

We use the planetsimulator (plasim), an intermediate complexity three-dimensional (3d) general circulation model (3d gcm), to study the dynamics of the exoplanet atmosphere and to derive the thermal phasecurves for different orbital inclination angles.Our simulations of the exoplanet are consistent with a day-side open ocean planet with a superrotating atmosphere.Because of the limited representation of the radiative transfer in the 3d model, we compute the spectrum of the exoplanet with an offline radiative transfer code with a spectrum resolution of 1 nm.This spectrum is used to derive the thermal phasecurves for different orbital inclination angles.The different thermal phase curves are used to evaluate observation conditions at ground level (e.g., elt) or in space(e.g., jwst).
