The VAST Survey - IV. A wide brown dwarf companion to the A3V star Delphini
R. J. De Rosa, J. Patience, K. Ward-Duong +10
We report the discovery of a wide co-moving substellar companion to the nearby ( pc) A3V star Delphini based on imaging and follow-up spectroscopic observations o…
The VAST Survey - III. The multiplicity of A-type stars within 75 pc
R. J. De Rosa, J. Patience, P. A. Wilson +11
With a combination of adaptive optics imaging and a multi-epoch common proper motion search, we have conducted a large volume-limited (D 75 pc) multiplicity survey of A-type…
Final A&T Stages of the Gemini Planet Finder
M. Hartung, B. Macintosh, L. Poyneer +16
The Gemini Planet Imager (GPI) is currently in its final Acceptance & Testing stages. GPI is an XAO system based on a tweeter & woofer architecture (43 & 9 actuators respectively a…
Determination of the inclination of the multi-planet hosting star HR8799 using asteroseismology
Duncan Wright, André-Nicolas Chené, Peter De Cat +6
Direct imaging of the HR8799 system was a major achievement in the study of exoplanets. HR8799 is a \,Doradus variable and asteroseismology can provide an independent constraint…
A Cold Neptune-Mass Planet OGLE-2007-BLG-368Lb: Cold Neptunes Are Common
T. Sumi, D. P. Bennett, I. A. Bond +104
We present the discovery of a Neptune-mass planet OGLE-2007-BLG-368Lb with a planet-star mass ratio of q=[9.5 +/- 2.1] x 10^{-5} via gravitational microlensing. The planetary devia…
Masses and Orbital Constraints for the OGLE-2006-BLG-109Lb,c Jupiter/Saturn Analog Planetary System
D. P. Bennett, S. H. Rhie, S. Nikolaev +70
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…
