Abstract:
The dependence on the temperature of photospheric line-depth ratios
(LDRs) in the spectral range 619.0-628.0nm is investigated by using a
sample of 174 ELODIE Archive stellar spectra of luminosity class from
V to III. The rotational broadening effect on LDRs is also studied. We
provide useful calibrations of effective temperature versus LDRs for
giant and main sequence stars with 3800≲Teff≲6000K and vsini in
the range 0-30km/s. We found that, with the exception of very few line
pairs, LDRs, measured at a spectral resolution as high as 42000,
depend on vsini and that, by neglecting the rotational broadening
effect, the Teff determination can be wrong by ∼100K in the worst
cases.
Description:
Averaged effective temperature (as obtained thanks to 15 line-depth
ratios), logarithm of the luminosity, and LDR values of the stellar
standard spectra not rotationally broadened.
