Spectroscopic characterisation of microlensing events Towards a new interpretation of OGLE-2011-BLG-0417
A. Santerne, J. -P. Beaulieu, B. Rojas Ayala +14
The microlensing event OGLE-2011-BLG-0417 is an exceptionally bright lens binary that was predicted to present radial velocity variation at the level of several km/s. Pioneer radia…
The First Circumbinary Planet Found by Microlensing: OGLE-2007-BLG-349L(AB)c
D. P. Bennett, S. H. Rhie, A. Udalski +79
We present the analysis of the first circumbinary planet microlensing event, OGLE-2007-BLG-349. This event has a strong planetary signal that is best fit with a mass ratio of $q \a…
OGLE-2012-BLG-0950Lb: The First Planet Mass Measurement from Only Microlens Parallax and Lens Flux
N. Koshimoto, A. Udalski, J. P. Beaulieu +38
We report the discovery of a microlensing planet OGLE-2012-BLG-0950Lb with the planet/host mass ratio of . A long term distortion detected in both MOA and…
Revisiting the microlensing event OGLE 2012-BLG-0026: A solar mass star with two cold giant planets
J. P. Beaulieu, D. P. Bennett, V. Batista +15
Two cold, gas giant planets orbiting a G-type main sequence star in the galactic disk have previously been discovered in the high magnification microlensing event OGLE-2012-BLG-002…
