  • We analyze MOA-2010-BLG-311, a high magnification (A max > 600) microlensing event with complete data coverage over the peak, making it very sensitive to planetary signals. We fit this event with both a point lens and a two-body lens model and find that the two-body lens model is a better fit but with only Δχ2 ~ 80. The preferred mass ratio between the lens star and its companion is q = 10–3.7 ± 0.1, placing the candidate companion in the planetary regime. Despite the formal significance of the… CONTINUE READING
