A Low-Mass Planet with a Possible Sub-Stellar-Mass Host in Microlensing Event MOA-2007-BLG-192
D. P. Bennett, I. A. Bond, A. Udalski +44
We report the detection of an extrasolar planet of mass ratio q ~ 2 x 10^(-4) in microlensing event MOA-2007-BLG-192. The best fit microlensing model shows both the microlensing pa…
Discovery of a Jupiter/Saturn Analog with Gravitational Microlensing
B. S. Gaudi, D. P. Bennett, A. Udalski +66
Searches for extrasolar planets have uncovered an astonishing diversity of planetary systems, yet the frequency of solar system analogs remains unknown. The gravitational microlens…
Recent results by the MOA group on gravitational microlensing
P. Yock, I. Bond, N. Rattenbury +25
Recent work by the MOA gravitational microlensing group is briefly described, including (i) the current observing strategy, (ii) use of a high-speed parallel computer for analysis…
Photometry of pulsating stars in the Magellanic Clouds as observed in the MOA project
J. B. Hearnshaw, I. A. Bond, N. J. Rattenbury +24
A review of the MOA (Microlensing Observations in Astrophysics) project is presented. MOA is a collaboration of approximately 30 astronomers from New Zealand and Japan established…
