A terrestrial planet candidate in a temperate orbit around Proxima Centauri
Guillem Anglada-Escudé, Pedro J. Amado, John Barnes +28
At a distance of 1.295 parsecs, the red-dwarf Proxima Centauri ( Centauri C, GL 551, HIP 70890, or simply Proxima) is the Sun's closest stellar neighbor and one of the best stud…
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-2015-BLG-0479LA,B: Binary Gravitational Microlens Characterized by Simultaneous Ground-based and Space-based Observation
C. Han, A. Udalski, A. Gould +60
We present a combined analysis of the observations of the gravitational microlensing event OGLE-2015-BLG-0479 taken both from the ground and by the {\it Spitzer Space Telescope}. T…
First simultaneous microlensing observations by two space telescopes: & reveal a brown dwarf in event OGLE-2015-BLG-1319
Y. Shvartzvald, Z. Li, A. Udalski +90
Simultaneous observations of microlensing events from multiple locations allow for the breaking of degeneracies between the physical properties of the lensing system, specifically…
Discovery of a Gas giant Planet in Microlensing Event OGLE-2014-BLG-1760
A. Bhattacharya, D. P. Bennett, I. A. Bond +41
We present the analysis of the planetary microlensing event OGLE-2014-BLG-1760, which shows a strong light curve signal due to the presence of a Jupiter mass-ratio planet. One unus…
The OGLE-III planet detection efficiency from six years of microlensing observations (2003 to 2008)
Y. Tsapras, M. Hundertmark, Ł. Wyrzykowski +17
We use six years (2003 to 2008) of Optical Gravitational Lensing Experiment III microlensing observations to derive the survey detection efficiency for a range of planetary masses…
