AGAPE : Gravitational microlensing effect to look for MACHOs towards M31
Abstract
Description
We report the discovery of a short-duration microlensing candidate in the Northern field of the POINT-AGAPE pixel lensing survey towards M31. The full-width at half-maximum timescale is very short (tfwhm = 1.8 days) and the source star has almost certainly been identified on HST images, allowing to infer an Einstein crossing time : te=10.4 days and a magnification at maximum : Amax=18.
