Astrophysicists offer New Research, Tool for Identifying Habitable Zones >>New light on S-type and P-type #binary stars and forms the basis for #BinHab, a new online tool that can be used to calculate the regions of binary systems favorable for life, commonly known as habitable zones. In #P-type systems the planet orbits both binary stars. In #S-type systems, the planet orbits only one of the stellar components with the 2nd component left to agitate the setting of the planet. The challenge is to properly consider two separate criteria consisting in the amounts of #stellar #radiation, which provides a favorable planetary climate for life, and the #gravitational influence of both stars on an existing planet, Cuntz said. >>Based on theory + observational data, incl NASAs #Kepler mission. ie Kepler-16, a binary system discovered in 2011, which is known to host a Saturn-type planet in a P-type system, implying that it orbits both stellar components. Additionally, the work has ramifications toward the field of astrobiology. Cuntz presents his work in a paper to be published in Jan 2015 in the Astrophysical Journal, a lead publication in this field of study. The paper is available online here. arxiv.org/abs/1409.3796 The first paper in the series was published in the journal in Jan. 2014 and is available here. arxiv.org/abs/1303.6645 phys.org/news/2014-12-astrophysicists-tool-habitable-zones.html#jCp
