Description:
In the past few years, the number of space missions with astrophysical
purposes has increased, with COROT, KEPLER, MOST and more recently
TESS. Two of the most important complementary tools for these missions
are the gravity and limb-darkening coefficients, hereafter GDC and
LDC. For the missions mentioned above, many calculations are available
to be used in several branches of stellar physics: synthetic light
curves of eclipsing binaries and planetary transits, stellar
diameters, line profiles in rotating stars, etc. see Claret & Bloemen
(2011, Cat. J/A+A/529/A75), Claret et al. (2014, Cat. J/A+A/567/A3),
Claret (2017, Cat. J/A+A/600/A30) and Claret (2018, Cat.
J/A+A/618/A20). However, as noted by Zhou et al. (2018, AJ,
submitted), these coefficients are not available for the GAIA mission.
The main objective of this Research Note is to provide the theoretical
calculations of the LDC and GDC for GAIA. We use two stellar
atmosphere models: ATLAS (plane-parallel) and PHOENIX with spherical
symmetry (Husser et al. 2013). The specific intensity distribution was
fitted using five approaches: linear, quadratic, square root,
logarithmic, and a more general one with four terms. These grids cover
19 metallicities ranging from 10-5 up to 10+1 solar abundances,
0≤logg≤6.0 and 1500K≤Teff≤50000K. The calculations of the
gravity-darkening coefficients were performed for all plane-parallel
ATLAS models.
