An empirical UBV RI JHK color-temperature calibration for stars. (2011)

Keywords : stars abundances - stars: fundamental parameters - stars: general

Abstract:A collection of Johnson/Cousins photometry for stars with known [Fe/H] is used to generate color-color relations that include the abundance dependence. Literature temperature and bolometric correction (BC) dependences are attached to the color relations. The JHK colors are transformed to the Bessell & Brett (1988PASP..100.1134B) homogenized system. The main result of this work is the tabulation of seven colors and the V-band BC as a function of Teff, logg, and [Fe/H] for -1.06<V-K<10.2 and an accompanying interpolation program. Improvements to the present calibration would involve filling photometry gaps, obtaining more accurate and on-system photometry, knowing better logg and [Fe/H] values, improving the statistics for data-impoverished ...(more)
