Sub-Saturn Planet MOA-2008-BLG-310Lb: Likely To Be In The Galactic Bulge

We report the detection of sub-Saturn-mass planet MOA-2008-BLG-310Lb and argue that it is the strongest candidate yet for a bulge planet. Deviations from the single-lens fit are smoothed out by finite-source effects and so are not…
