TL;DR: The OGLE-2003-BLG-262 microlensing event as mentioned in this paper, a relatively short (tE ¼ 12:5 � 0:1 day) microlens event generated by a point-mass lens transiting the face of a K giant source in the Galactic bulge, is the only published event to date in which the lens transits the source.

TL;DR: In this paper, the authors presented the first measurement of the planet frequency beyond the "snow line," for the planet-to-star mass-ratio interval during 2005-2008 microlensing events during the survey-plus-follow-up high-magnification channel.

OGLE-2003-BLG-262: Finite-Source Effects from a Point-Mass Lens

TL;DR: The OGLE-2003-BLG-262 microlensing event as mentioned in this paper was generated by a point-mass lens transiting the face of a K giant source in the Galactic bulge, and the resulting finite-source effects were used to measure the angular Einstein radius, theta_E=195+-17muas, and so constrain the lens mass to the fullwidth half-maximum interval 0.08 < M/M_sun < 0.54.

TL;DR: Two planets with masses that could not have been detected with other techniques are identified; their discovery from only six confirmed microlensing planet detections suggests that solar system analogs may be common.

TL;DR: In this paper, the authors detect a Neptune mass ratio (q 8? 10-5) planetary companion to the lens star in the extremely high magnification (A ~ 800) microlensing event OGLE-2005-BLG-169.
