Washington, July 11, 2016, 10:05 – REGNUM American astrophysicist identified groups of stars, creating conditions for the emergence and maintenance of on planets orbiting them life, reports portal arXiv.org.
The most suitable for the search of possible forms of life are the vicinity of stars range from late spectral class G (like the Sun) until mid-cycle development of K (Star colder and larger than the Sun), with surface temperatures equal 4900-5300 Kelvin.
Taking into account a variety of factors, the scientists introduced a parameter called HabPREP (Habitable-Planetary- Real-Estate Parameter), which determines the measure of the suitability of the stars for the appearance on its planets life.
According to the authors, the emergence of life around red dwarfs, which are the most common stars in the universe, the least likely.
the study confirmed the previously published hypothesis that the most suitable for extraterrestrial life are the orbits of old stars of class G and class of young stars K.
