The Gemini NICI Planet-Finding Campaign
Michael C. Liu, Zahed Wahhaj, Beth A. Biller +21
Our team is carrying out a multi-year observing program to directly image and characterize young extrasolar planets using the Near-Infrared Coronagraphic Imager (NICI) on the Gemin…
The Gemini NICI Planet-Finding Campaign: The Frequency of Planets around Young Moving Group Stars
Beth A. Biller, Michael C. Liu, Zahed Wahhaj +18
We report results of a direct imaging survey for giant planets around 80 members of the Beta Pic, TW Hya, Tucana-Horologium, AB Dor, and Hercules-Lyra moving groups, observed as pa…
Detectability of Terrestrial Planets in Multi-Planet Systems: Preliminary Report
Wesley A. Traub, Charles Beichman, Andrew F. Boden +21
We ask if Earth-like planets (terrestrial mass and habitable-zone orbit) can be detected in multi-planet systems, using astrometric and radial velocity observations. We report here…
The Transiting Exoplanet Survey Satellite
George R. Ricker, Joshua N. Winn, Roland Vanderspek +55
The Transiting Exoplanet Survey Satellite (TESS) will search for planets transiting bright and nearby stars. TESS has been selected by NASA for launch in 2017 as an Astrophysics Ex…
The Gemini NICI Planet-Finding Campaign: Discovery of a Close Substellar Companion to the Young Debris Disk Star PZ Tel
Beth A. Biller, Michael C. Liu, Zahed Wahhaj +24
We report the discovery of a tight substellar companion to the young solar analog PZ Tel, a member of the Beta Pictoris moving group observed with high contrast adaptive optics ima…
On the Surface Heating of Synchronously-Spinning Short-Period Jovian Planets
Andreas Burkert, Douglas Lin, Peter Bodenheimer +2
We consider the atmospheric flow on short-period extra-solar planets through two-dimensional numerical simulations of hydrodynamics with radiation transfer. One side is always expo…
