The angular sizes of dwarf stars and subgiants. Surface brightness relations calibrated by interferometry

Astronomy and Astrophysics, 2004, vol. 426, pp. 297-307

Référence ADS : 2004A&A...426..297K

Résumé :

The availability of a number of new interferometric measurements of Main Sequence and subgiant stars makes it possible to calibrate the surface brightness relations of these stars using exclusively direct angular diameter measurements. These empirical laws make it possible to predict the limb darkened angular diameters theta<SUB>LD</SUB> of dwarfs and subgiants using their dereddened Johnson magnitudes, or their effective temperature. The smallest intrinsic dispersions of sigma
