Empirically Constrained Color-Temperature Relations. I. BV ( RI ) C

Abstract

This investigation presents a set of transformations to Johnson B-V, Cousins V-R, and Cousins V-I, as well as bolometric corrections to V, for [Fe/H]=-3, -2, -1, -0.5, 0.0, and +0.3 and, in each case, values of logg from -0.5 to 5.0 for 3000 K =8000 K) and from MARCS model atmospheres at intermediate temperatures (from 7000 K down to a temperature in the range 4000 K
