Abstract:
One of the most reliable means of studying the stellar interior is
through the apsidal motion in double line eclipsing binary systems
since these systems present errors in masses, radii, and effective
temperatures of only a few per cent. On the other hand, the
theoretical values of the apsidal motion to be compared with the
observed values depend on the stellar masses of the components and
more strongly on their radii (fifth power). The main objective of this
work is to make available grids of evolutionary stellar models that,
in addition to the traditional parameters (e.g. age, mass, logg,
Teff), also contain the necessary parameters for the theoretical study
of apsidal motion and tidal evolution. This information is useful for
the study of the apsidal motion in eclipsing binaries and their tidal
evolution, and can also be used for the same purpose in exoplanetary
systems.
Description:
All models were computed using the MESA package. We consider core
overshooting for models with masses ≥1.2M☉. For the amount of
core overshooting adopted a recent relationship for mass times core
overshooting. We adopted for the mixing-length parameter αMLT
the value 1.84 (the solar-calibrated value). Mass loss was taken into
account in two evolutionary phases. The models were followed from the
pre-main sequence phase to the white dwarf (WD) stage.
The evolutionary models containing age, luminosity, logg, and Teff,
as well as the first three harmonics of the internal stellar structure
(k2, k3, and k4), the radius of gyration β y, and the
dimensionless variable α, related to gravitational potential
energy, are presented in 69 tables covering three chemical
compositions: [Fe/H] = -0.50, 0.00, and 0.50. Additional models with
different input physics are available.
