Stellar Limb Darkening Measurement from Gravitational Microlensing
Observations


David Heyrovsky, Charles University Prague

Observations of caustic-crossing Galactic gravitational microlensing
events provide a unique opportunity to study the atmospheres of the
lensed stars.  Here we demonstrate the influence of the star's limb
darkening on the microlensing light curve and introduce an optimal
method for its measurement.  We analyze several observed microlensing
events and present the measured limb darkening profiles of the lensed
stars.
