Masses and Orbital Constraints for the OGLE-2006-BLG-109Lb,c Jupiter/Saturn Analog Planetary System (2009)

Bennett, D. P., Rhie, S. H., Nikolaev, S., Gaudi, B. S., Udalski, A., Gould, A., ...

We present a new analysis of the Jupiter+Saturn analog system, OGLE-2006-BLG-109Lb,c, which was the first double planet system discovered with the gravitational microlensing method. This is the only...

Mass measurement of a single unseen star and planetary detection efficiency for OGLE 2007-BLG-050 (2009)

Batista, V., Dong, Subo, Gould, A., Beaulieu, J. P., Cassan, A., Christie, G. W., ...

We analyze OGLE-2007-BLG-050, a high magnification microlensing event (A ~ 432) whose peak occurred on 2 May, 2007, with pronounced finite-source and parallax effects. We compute planet detection...

OGLE-2005-BLG-071Lb, the Most Massive M Dwarf Planetary Companion? (2009)

Dong, Subo, Gould, Andrew, Udalski, Andrzej, Anderson, Jay, Christie, G. W., Gaudi, B. S., ...

We combine all available information to constrain the nature of OGLE-2005-BLG-071Lb, the second planet discovered by microlensing and the first in a high-magnification event. These include...

OGLE-2005-BLG-071Lb, the Most Massive M Dwarf Planetary Companion? (2009)

Christie, G.W., Gaudi, B.S., Kubiak, M., Szymanski, M.K., Pietrzynski, G., Soszynski, I., ...

We combine all available information to constrain the nature of OGLE-2005-BLG-071Lb, the second planet discovered by microlensing and the first in a high-magnification event. These include...

Microlensing Event MOA-2007-BLG-400: Exhuming the Buried Signature of a Cool, Jovian-Mass Planet (2008)

Dong, Subo, Bond, I. A., Gould, A., Kozlowski, Szymon, Miyake, N., Gaudi, B. S., ...

We report the detection of the cool, Jovian-mass planet MOA-2007-BLG-400Lb. The planet was detected in a high-magnification microlensing event (with peak magnification A_max = 628) in which the...

OGLE-2005-BLG-071Lb, the Most Massive M-Dwarf Planetary Companion? (2008)

Dong, Subo, Gould, Andrew, Udalski, Andrzej, Anderson, Jay, Christie, G. W., Gaudi, B. S., ...

We combine all available information to constrain the nature of OGLE-2005-BLG-071Lb, the second planet discovered by microlensing and the first in a high-magnification event. These include...

Discovery of a Jupiter/Saturn Analog with Gravitational Microlensing (2008)

Gaudi, B. S., Bennett, D. P., Udalski, A., Gould, A., Christie, G. W., Maoz, D., ...

Searches for extrasolar planets have uncovered an astonishing diversity of planetary systems, yet the frequency of solar system analogs remains unknown. The gravitational microlensing planet search...

First Space-Based Microlens Parallax Measurement: Spitzer Observations of OGLE-2005-SMC-001 (2007)

Dong, Subo, Udalski, A., Gould, A., Reach, W. T., Christie, G. W., Boden, A. F., ...

We combine Spitzer and ground-based observations to measure the microlens parallax of OGLE-2005-SMC-001, the first such space-based determination since S. Refsdal proposed the idea in 1966. The...

Detecting Exoplanets by Gravitational Microlensing using a Small Telescope (2006)

Christie, G. W.

Gravitational microlensing is a new technique that allows low-mass exoplanets to be detected at large distances of ~7kpc. This paper briefly outlines the principles of the method and describes the...

Microlens OGLE-2005-BLG-169 Implies Cool Neptune-Like Planets are Common (2006)

Gould, A., Udalski, A., An, D., Bennett, D. P., Dong, S., ...

We detect a Neptune mass-ratio (q~8e-5) planetary companion to the lens star in the extremely high-magnification (A~800) microlensing event OGLE-2005-BLG-169. If the parent is a main-sequence star,...
