Kepler-22b: A 2.4 Earth-radius Planet in the Habitable Zone of a Sun-like Star
William J. Borucki, David G. Koch, Natalie Batalha +80
A search of the time-series photometry from NASA's Kepler spacecraft reveals a transiting planet candidate orbiting the 11th magnitude G5 dwarf KIC 10593626 with a period of 290 da…
The Dynamical Mass and Three-Dimensional Orbit of HR7672B: A Benchmark Brown Dwarf with High Eccentricity
Justin R. Crepp, John Asher Johnson, Debra A. Fischer +10
The companion to the G0V star HR7672 directly imaged by Liu et al. (2002) has moved measurably along its orbit since the discovery epoch, making it possible to determine its dynami…
Characterizing the Cool KOIs II. The M Dwarf KOI-254 and its Hot Jupiter
John Asher Johnson, J. Zachary Gazak, Kevin Apps +12
We report the confirmation and characterization of a transiting gas giant planet orbiting the M dwarf KOI-254 every 2.455239 days, which was originally discovered by the Kepler mis…
The Pan-Pacific Planet Search. I. A Giant Planet Orbiting 7 CMa
R. A. Wittenmyer, M. Endl, L. Wang +3
We introduce the Pan-Pacific Planet Search, a survey of 170 metal-rich Southern hemisphere subgiants using the 3.9m Anglo-Australian Telescope. We report the first discovery from t…
Kepler 18-b, c, and d: A System Of Three Planets Confirmed by Transit Timing Variations, Lightcurve Validation, Spitzer Photometry and Radial Velocity Measurements
William D. Cochran, Daniel C. Fabrycky, Guillermo Torres +51
We report the detection of three transiting planets around a Sunlike star, which we designate Kepler-18. The transit signals were detected in photometric data from the Kepler satel…
Spin-Orbit Alignment for the Circumbinary Planet Host Kepler-16A
Joshua N. Winn, Simon Albrecht, John Asher Johnson +31
Kepler-16 is an eccentric low-mass eclipsing binary with a circumbinary transiting planet. Here we investigate the angular momentum of the primary star, based on Kepler photometry…
A High Eccentricity Component in the Double Planet System Around HD 163607 and a Planet Around HD 164509
Matthew J. Giguere, Debra A. Fischer, Andrew W. Howard +7
We report the detection of three new exoplanets from Keck Observatory. HD 163607 is a metal-rich G5IV star with two planets. The inner planet has an observed orbital period of 75.2…
M2K: II. A Triple-Planet System Orbiting HIP 57274
Debra A. Fischer, Eric Gaidos, Andrew Howard +14
Doppler observations from Keck Observatory have revealed a triple planet system orbiting the nearby mid-type K dwarf, HIP 57274. The inner planet, HIP 57274b, is a super-Earth with…
Retired A Stars and Their Companions: Eighteen New Jovian Planets
John Asher Johnson, Christian Clanton, Andrew W. Howard +9
We report the detection of eighteen Jovian planets discovered as part of our Doppler survey of subgiant stars at Keck Observatory, with follow-up Doppler and photometric observatio…
HAT-P-31b,c: A Transiting, Eccentric, Hot Jupiter and a Long-Period, Massive Third-Body
David M. Kipping, Joel Hartman, Gáspár Á. Bakos +21
We report the discovery of HAT-P-31b, a transiting exoplanet orbiting the V=11.660 dwarf star GSC 2099-00908. HAT-P-31b is the first HAT planet discovered without any follow-up pho…
Two Upper Limits on the Rossiter-McLaughlin Effect, with Differing Implications: WASP-1 has a High Obliquity and WASP-2 is Indeterminate
Simon Albrecht, Joshua N. Winn, John Asher Johnson +9
We present precise radial-velocity measurements of WASP-1 and WASP-2 throughout transits of their giant planets. Our goal was to detect the Rossiter-McLaughlin (RM) effect, the ano…
Estimates of the Planet Yield from Ground-Based High-Contrast Imaging Observations as a Function of Stellar Mass
Justin R. Crepp, John Asher Johnson
We use Monte Carlo simulations to estimate the number of extrasolar planets that are directly detectable in the solar-neighborhood using current and forthcoming high-contrast imagi…
HAT-P-30b: A transiting hot Jupiter on a highly oblique orbit
John Asher Johnson, J. N. Winn, J. D. Hartman +20
We report the discovery of HAT-P-30b, a transiting exoplanet orbiting the V=10.419 dwarf star GSC 0208-00722. The planet has a period P=2.810595+/-0.000005 d, transit epoch Tc = 24…
Planet Occurrence within 0.25 AU of Solar-type Stars from Kepler
Andrew W. Howard, Geoffrey W. Marcy, Stephen T. Bryson +59
We report the distribution of planets as a function of planet radius (R_p), orbital period (P), and stellar effective temperature (Teff) for P < 50 day orbits around GK stars. Thes…
KEPLER's First Rocky Planet: Kepler-10b
Natalie M. Batalha, William J. Borucki, Stephen T. Bryson +49
NASA's Kepler Mission uses transit photometry to determine the frequency of earth-size planets in or near the habitable zone of Sun-like stars. The mission reached a milestone towa…
The Pan-Pacific Planet Search: A southern hemisphere search for planets orbiting evolved massive stars
Robert A. Wittenmyer, John A. Johnson, Liang Wang +1
The vast majority of known extrasolar planets orbit stars with a narrow range of masses (0.7-1.3 M_sun). Recent years have seen rapid growth in our knowledge about the properties o…
