Simultaneous Bayesian estimation of distances and ages from isochrones: SDSS and solar neighborhood FGK stars
Abstract
By using a procedure based on the Bayesian probability theory we computed reliable and self-consistent estimates of absolute magnitude and age for about 2000 FKG spectral-type stars from SDSS-DR5, ELODIE, and INDO-US surveys, with effective temperature, surface gravity, and metallicity values homogeneously derived.
