Abstract:
The evolution of massive stars is not fully understood. The relation
between different types of evolved massive stars is not clear, and the
role of factors such as binarity, rotation or magnetism needs to be
quantified.
Several groups make available the results of 1D single stellar
evolution calculations in the form of evolutionary tracks and
isochrones. They use different stellar evolution codes for which the
input physics and its implementation varies. In this paper, we aim at
comparing the currently available evolutionary tracks for massive
stars. We focus on calculations aiming at reproducing the evolution of
Galactic stars. Our main goal is to highlight the uncertainties on the
predicted evolutionary paths.
We compute stellar evolution models with the codes MESA and STAREVOL.
We compare our results with those of four published grids of massive
stellar evolution models (Geneva, STERN, Padova and FRANEC codes). We
first investigate the effects of overshooting, mass loss, metallicity,
chemical composition. We subsequently focus on rotation. Finally, we
compare the predictions of published evolutionary models with the
observed properties of a large sample of Galactic stars.
Description:
Tables of evolutionary models for massive stars.
The files m*_stol.dat correspond to models computed with the code
STAREVOL. The files m*_mesa.dat correspond to models computed with the
code MESA. For each code, models with initial masses equal to 7, 9,
15, 20, 25, 40 and 60M☉ are provided. No rotation is included.
The overshooting parameter f is equal to 0.01. The metallicity is
solar.
