OGLE 2008-BLG-290: an accurate measurement of the limb darkening of a galactic bulge K Giant spatially resolved by microlensing

Abstract

The results of study of the microlensing event OGLE 2008-BLG-290 are presented. Thirteen different telescopes have covered this event in eight different photometric bands.

Linear limb-darkening coefficients of the source were obtained in six photometric bands and as well as estimate of the source effective temperature.
