摘要：We present the analysis of the anomalous microlensing event OGLE-2007-BLG-472, including
a fit of a binary lens model to the data. This event is a low-magnification and highly blended
event with a pair of caustic crossings separated by 2.7 days. From our best-fit model and a chosen
Galactic model, we derive Bayesian probability densities for physical properties of the planet and
its host star. We derive a secondary mass of 9.74+11.70
−5.34 MJ, which lies near the formal frontier
between the planetary and brown dwarf mass regimes (13 MJ)
