Kepler-22B: A 2.4 Earth-Radius Planet In The Habitable Zone Of A Sun-Like Star
(2012-02)
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 days. The characteristics of the host star ...
Elemental Abundances Of Solar Sibling Candidates
(2014-06)
Dynamical information along with survey data on metallicity and in some cases age have been used recently by some authors to search for candidates of stars that were born in the cluster where the Sun formed. We have acquired ...
Hd 91669B: A New Brown Dwarf Candidate From The McDonald Observatory Planet
(2009-03)
We report the detection of a brown dwarf candidate orbiting the metal-rich K dwarf HD 91669, based on radial-velocity data from the McDonald Observatory Planet Search. HD 91669b is a substellar object in an eccentric orbit ...
Characteristics Of Kepler Planetary Candidates Based On The First Data Set
(2011-02)
In the spring of 2009, the Kepler Mission commenced high-precision photometry on nearly 156,000 stars to determine the frequency and characteristics of small exoplanets, conduct a guest observer program, and obtain ...
The Spin-Orbit Alignment of the HD 17156 Transiting Eccentric Planetary System
(2008-08)
We present high- precision radial velocity observations of HD 17156 during a transit of its eccentric Jovian planet. In these data, we detect the Rossiter- McLaughlin effect, which is an apparent perturbation in the velocity ...
The Pan-Pacific Planet Search. II. Confirmation Of A Two-Planet System Around Hd 121056
(2015-02)
Precise radial velocities from the Anglo-Australian Telescope (AAT) confirm the presence of a rare short-period planet around the K0 giant HD 121056. An independent two-planet solution using the AAT data shows that the ...
The Neptune-Sized Circumbinary Planet Kepler-38B
(2012-10)
We discuss the discovery and characterization of the circumbinary planet Kepler-38b. The stellar binary is single-lined, with a period of 18.8 days, and consists of a moderately evolved main-sequence star (M-A = 0.949+/-0.059 ...
The Discovery Of Hd 37605C And A Dispositive Null Detection Of Transits Of Hd 37605B
(2012-12)
We report the radial velocity discovery of a second planetary mass companion to the K0 V star HD 37605, which was already known to host an eccentric, P similar to 55 days Jovian planet, HD 37605b. This second planet, HD ...
Kepler-20: A Sun-Like Star With Three Sub-Neptune Exoplanets And Two Earth-Size Candidates
(2012-04)
We present the discovery of the Kepler-20 planetary system, which we initially identified through the detection of five distinct periodic transit signals in the Kepler light curve of the host star 2MASS J19104752+4220194. ...
Retired A Stars and Their Companions. VII. 18 New Jovian Planets
(2011-12)
We report the detection of 18 Jovian planets discovered as part of our Doppler survey of subgiant stars at Keck Observatory, with follow-up Doppler and photometric observations made at McDonald and Fairborn Observatories, ...
