Grids of stellar models including second harmonic and colours: Solar composition
Grids of stellar evolution are required in many fields of
astronomy/astrophysics, such as planet hosting stars, binaries, clusters,
chemically peculiar stars, etc. In this study, a grid of stellar evolution
models with updated ingredients and {recently determined solar abundaces} is
presented. The solar values for the initial abundances of hydrogen, heavy
elements and mixing-length parameter are 0.0172, 0.7024 and 1.98, respectively.
The mass step is small enough (0.01 M) that interpolation for a given
star mass is not required. The range of stellar mass is 0.74 to 10.00
M. We present results in different forms of tables for easy and general
application. The second stellar harmonic, required for analysis of apsidal
motion of eclipsing binaries, is also listed. We also construct rotating models
to determine effect of rotation on stellar structure and derive fitting formula
for luminosity, radius and the second stellar harmonic as a function of
rotational parameter. We also compute and list colours and bolometric
corrections of models required for transformation between theoretical and
observational results. The results are tested for the Sun, the Hyades cluster,
the slowly rotating chemically peculiar Am stars and the eclipsing binaries
with apsidal motion. The theoretical and observational results along isochrones
are in good agreement. The grids are also applicable to rotating stars provided
that equatorial velocity is given.Comment: 13 Figures 21 pages. Accepted by RA
