Climate and radiative properties of a tidally-locked planet around Proxima Centauri.

Red dwarf stars are the most common type of stars in our Galaxy. That's why the search for habitable exoplanets is focused on such stars, although high X-UV fluxes and extreme space weather events can represent a decisive impediment to the presence of life forms. We investigate the climate of the tidally locked Earth-like planet orbiting around Proxima Centauri via the 3-D atmospheric general circulation model PlaSim and the 1-D radiative transfer model uvspec. A planetary preindustrial atmosphere, circular orbit and null axial tilt are assumed. The thermal emission of the planet-host star system is calculated in the infrared region.
