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…
