Potential Direct Single-Star Mass Measurement
H. Ghosh
We analyze the lightcurve of the microlensing event OGLE-2003-BLG-175/MOA-2003-BLG-45 and show that it has two properties that, when combined with future high resolution astrometry…

OGLE-2003-BLG-238: Microlensing Mass Estimate of an Isolated Star
Guangfei Jiang, D. L. DePoy, A. Gal-Yam +38
Microlensing is the only known direct method to measure the masses of stars that lack visible companions. In terms of microlensing observables, the mass is given by M=(c^2/4G)\tild…
