Ingrosso, G; Calchi Novati, S; De Paolis, F; Jetzer, P; Nucita, A; Zakharov, A (2011). Search for exoplanets in M31 with pixel-lensing and the PA-99-N2 event revisited. General Relativity and Gravitation, 43(4):1047-1060.
Several exoplanets have been detected towards the Galactic bulge with the microlensing technique. We show that exoplanets in M31 may also be detected with the pixel-lensing method, if telescopes making high cadence observations of an ongoing microlensing event are used. Using a Monte Carlo approach we find that the mean mass for detectable planetary systems is about 2 M J. However, even small mass exoplanets () can cause significant deviations, which are observable with large telescopes. We reanalysed the POINT-AGAPE microlensing event PA-99-N2. First, we test the robustness of the binary lens conclusion for this light curve. Second, we show that for such long duration and bright microlensing events, the efficiency for finding planetary-like deviations is strongly enhanced with respect to that evaluated for all planetary detectable events.
