Microlensing Characterization of Wide-Separation Planets

Cheongho Han, B. Scott Gaudi, Jin H. An +1

With their excellent photometric precision and dramatic increase in monitoring frequency, future microlensing survey experiments are expected to be sensitive to very short time-sca…

Prospects for the Detection of Earth-Mass Planets

Andrew Gould, B. Scott Gaudi, Cheongho Han

We compare potential state-of-the-art experiments for detecting Earth-mass planets around main-sequence stars using radial velocities, transits, astrometry, and microlensing. For c…

Constraints on Planetary Companions in the Magnification A=256 Microlensing Event: OGLE-2003-BLG-423

Jaiyul Yoo, D. L. DePoy, A. Gal-Yam +16

We develop a new method of modeling microlensing events based on a Monte Carlo simulation that incorporates both a Galactic model and the constraints imposed by the observed charac…

The Many Possible Interpretations of Microlensing Event OGLE-2002-BLG-055

B. Scott Gaudi, Cheongho Han

Microlensing event OGLE-2002-BLG-055 is characterized by a smooth, slightly asymmetric single-lens curve with an isolated, secure data point that is ~0.6 magnitudes brighter than n…

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…
