Kepler Planet-Detection Mission: Introduction and First Results
The planetary findings derived from the first six weeks of observations with the Kepler mission are summarized, which include the detection of five new exoplanets, which confirm the existence of planets with densities substantially lower than those predicted for gas giant planets.
A terrestrial planet candidate in a temperate orbit around Proxima Centauri
Observations reveal the presence of a small planet with a minimum mass of about 1.3 Earth masses orbiting Proxima with a period of approximately 11.2 days at a semi-major-axis distance of around 0.05 astronomical units.
Characteristics of planetary candidates observed by Kepler, II: Analysis of the first four months of data
On 2011 February 1 the Kepler mission released data for 156,453 stars observed from the beginning of the science observations on 2009 May 2 through September 16. There are 1235 planetary candidates
Transiting Exoplanet Survey Satellite (TESS)
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 Explorer mission.
Evidence for a Long-Period Planet Orbiting ∊ Eridani
High-precision radial velocity (RV) measurements spanning the years 1980.8‐2000.0 are presented for the nearby (3.22 pc) K2 V star e Eri. These data, which represent a combination of six independent
An abundance of small exoplanets around stars with a wide range of metallicities
Spectroscopic metallicities of the host stars of 226 small exoplanet candidates discovered by NASA's Kepler mission are reported, finding that planets with radii less than four Earth radii form around host stars with a wide range of metallicities (but on average a metallicity close to that of the Sun), whereas large planets preferentially form around stars with higher metallicities.
A Planetary Companion to γ Cephei A
We report on the detection of a planetary companion in orbit around the primary star of the binary system γ Cephei. High-precision radial velocity measurements using four independent data sets
Detection of a NEPTUNE-mass planet in the $ρ^{1}$ Cancri system using the Hobby-Eberly Telescope
We report the detection of the lowest mass extrasolar planet yet found around a Sun-like star—a planet with an M sin i of only 14.21 ± 2.91 M⊕ in an extremely short period orbit (P = 2.808 days)
Masses, Radii, and Orbits of Small Kepler Planets: The Transition From Gaseous to Rocky Planets
We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are 49 planet candidates around these stars, including 42 detected through transits and 7 revealed by precise
Transiting circumbinary planets Kepler-34 b and Kepler-35 b
The observed rate of circumbinary planets in this sample implies that more than ∼1% of close binary stars have giant planets in nearly coplanar orbits, yielding a Galactic population of at least several million.
