Confirmation of the OGLE-2005-BLG-169 planet signature and characteristics with lens-source proper motion detection
V. Batista, J. -P. Beaulieu, D. P. Bennett +4
We present Keck NIRC2 high angular resolution adaptive optics observations of the microlensing event OGLE-2005-BLG-169, taken 8.21 years after the discovery of this planetary syste…
Can the masses of isolated planetary-mass gravitational lenses be measured by terrestrial parallax?
M. Freeman, L. C. Philpott, F. Abe +22
Recently Sumi et al. (2011) reported evidence for a large population of planetary-mass objects (PMOs) that are either unbound or orbit host stars in orbits > 10 AU. Their result wa…
A possible binary system of a stellar remnant in the high magnification gravitational microlensing event OGLE-2007-BLG-514
N. Miyake, A. Udalski, T. Sumi +78
We report the extremely high magnification (A > 1000) binary microlensing event OGLE-2007-BLG-514. We obtained good coverage around the double peak structure in the light curve via…
OGLE-2008-BLG-510: first automated real-time detection of a weak microlensing anomaly - brown dwarf or stellar binary?
V. Bozza, M. Dominik, N. J. Rattenbury +103
The microlensing event OGLE-2008-BLG-510 is characterised by an evident asymmetric shape of the peak, promptly detected by the ARTEMiS system in real time. The skewness of the ligh…
