[80.10U] Disk Source Geometry from Microlensing Light Curves

J. Bury (Dept. of Physics, U. Oregon), S. E. Levine (USNO, Flagstaff)

The geometrical signature in a microlensing light curve of a disk source with variable size, inclination, and position angle is treated. We focus specifically on events where the source does not pass over caustics. Through the analysis of synthetic light curve data we show that a least-squares fitting routine can be used to estimate the geometrical properties of the source. As observations improve, we should be able to reconstruct the geometry of sources that were previously unresolvable. J. B. would like to thank the NSF for support through the NAU REU program (NSF Grant No. 9988007), and USNO for hospitality.
