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…
The Mass of the MACHO-LMC-5 Lens Star
Andrew Gould, David P. Bennett, David R. Alves
We combine the available astrometric and photometric data for the 1993 microlensing event MACHO-LMC-5 to measure the mass of the lens, M=0.097 +/- 0.016 Msun. This is the most prec…
OGLE 2003-BLG-235/MOA 2003-BLG-53: A planetary microlensing event
I. A. Bond, A. Udalski, M. Jaroszynski +29
We present observations of the unusual microlensing event OGLE 2003-BLG-235/MOA 2003-BLG-53. In this event a short duration (~7 days) low amplitude deviation in the light curve due…
The Detection of Terrestrial Planets via Gravitational Microlensing: Space vs. Ground-based Surveys
David P. Bennett
I compare an aggressive ground-based gravitational microlensing survey for terrestrial planets to a space-based survey. The Ground-based survey assumes a global network of very wid…
MOA 2003-BLG-37: A Bulge Jerk-Parallax Microlens Degeneracy
B. -G. Park, D. L. DePoy, B. S. Gaudi +25
We analyze the Galactic bulge microlensing event MOA-2003-BLG-37. Although the Einstein timescale is relatively short, t_e=43 days, the lightcurve displays deviations consistent wi…
