Habitability around Single Stars and in Multiple Stellar Systems

Habitability, i.e., the planet’s potential to develop and sustain life, is a topic of intense research, encompassing both favorable conditions as, e.g., the size and stability of the stellar climatological habitable zones as well as adverse forcings. The latter encompass numerous factors including (but not limited to) intense UV and X-ray radiation, which have the potential of evaporating planetary atmospheres. These constituents apply to both planets around single stars and those hosted by multiple stellar systems. Regarding the latter, the analysis of planetary habitability is, however, more complex as, e.g., the presence of multiple stellar components affects both the extent and time-dependency of the habitable zones and the domains of planetary orbital stability. Recent progress has been made in regard to binary systems, pertaining to both S-type and P-type planetary orbits. Detailed results have been obtained for a large variety of observed and theoretical systems, including systems detected by the Kepler mission. I intend to summarize recent results and to convey perspectives of future research.
