Bonn Optimized Stellar Tracks (BoOST)

Massive and very massive stars can play important roles in stellar populations by ejecting strong winds exploding energetic phenomena. It is therefore imperative that their behavior be properly accounted for synthetic model populations. We present nine grids of evolutionary sequences, together with finely resolved interpolated sequences populations, 9-500 Msun metallicities ranging from Galactic metallicity down to 1/250 Zsun. The models were computed the Bonn code consistent physical ingredients, covering core hydrogen- helium-burning phases. interpolation population synthesis performed our newly developed routine 'synStars'. Eight represent slowly rotating a normal or classical path, while one grid represents fast-rotating, chemically homogeneously evolving models. contain data on wind properties such as estimated velocity kinetic energy wind, well common parameters mass, radius, surface temperature, luminosity, mass-loss rate, abundances 34 isotopes. also provide estimates helium carbon-oxygen mass calculating remnants. Optimized Stellar Tracks (BoOST) project published simple tables include models, tracks, Covering broadest range any star sets date, BoOST ideal further scientific applications formation studies both low- high-redshift galaxies.
