A CATALOG OF STELLAR EVOLUTION PROFILES AND THE EFFECTS OF VARIABLE COMPOSITION ON HABITABLE SYSTEMS


Abstract We present stellar evolution models for 0.5 - 1.2 M[subscript ⊙] at scaled metallicities of 0.1 - 1.5 Z[subscript ⊙] and O/Fe values of 0.44 - 2.28 O/Fe[subscript ⊙]. The time dependent evolution of habitable zone boundaries are calculated for each stellar evolution track based on stellar mass, effective temperature, and luminosity parameterizations. The rate of change of stellar surface quantities and the surrounding habitable zone position are strong functions of all three quantities explored. The range of orbits that remain continuously habitable, or habitable for at least 2 Gyr, are provided. The results show that the detailed chemical characterization of exoplanet host stars and a consideration of their evolutionary history are necessa... (more)
