Abstract

Aims. We analyze OGLE-2007-BLG-050, a high magnification microlensing event () whose peak occurred on 2 May, 2007, with pronounced finite-source and parallax effects. We compute planet detection efficiencies for this event in order to determine its sensitivity to the presence of planets around the lens star.Methods. Both finite-source and parallax effects permit a measurement of the angular Einstein radius mas and the parallax , leading to an estimate of the lens mass and its distance to the observer kpc. This is only the second determination of a reasonably precise (
