Planetary Candidates Observed by Kepler IV: Planet Sample From Q1-Q8 (22 Months)

Christopher J. Burke, Stephen T. Bryson, F. Mullally +37

We provide updates to the Kepler planet candidate sample based upon nearly two years of high-precision photometry (i.e., Q1-Q8). From an initial list of nearly 13,400 Threshold Cro…

What asteroseismology can do for exoplanets: Kepler-410A b is a Small Neptune around a bright star, in an eccentric orbit consistent with low obliquity

Vincent Van Eylen, Mikkel N. Lund, Victor Silva Aguirre +12

We confirm the Kepler planet candidate Kepler-410b (KOI-42b) as a Neptune sized exoplanet on a 17.8 day, eccentric orbit around the bright (Kp = 9.4) star Kepler-410A. This is the…

Accurate parameters of the oldest known rocky-exoplanet hosting system: Kepler-10 revisited

Alexandra Fogtmann-Schulz, Brian Hinrup, Vincent Van Eylen +4

Since the discovery of Kepler-10, the system has received considerable interest because it contains a small, rocky planet which orbits the star in less than a day. The system's par…

Revised Stellar Properties of Kepler Targets for the Quarter 1-16 Transit Detection Run

Daniel Huber, Victor Silva Aguirre, Jaymie M. Matthews +19

We present revised properties for 196,468 stars observed by the NASA Kepler Mission and used in the analysis of Quarter 1-16 (Q1-Q16) data to detect and characterize transiting exo…

Stellar Spin-Orbit Misalignment in a Multiplanet System

Daniel Huber, Joshua A. Carter, Mauro Barbieri +32

Stars hosting hot Jupiters are often observed to have high obliquities, whereas stars with multiple co-planar planets have been seen to have low obliquities. This has been interpre…

The PLATO 2.0 Mission

H. Rauer, C. Catala, C. Aerts +159

PLATO 2.0 has recently been selected for ESA's M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it…

Kepler-63b: A Giant Planet in a Polar Orbit around a Young Sun-like Star

Roberto Sanchis-Ojeda, Joshua N. Winn, Geoffrey W. Marcy +19

We present the discovery and characterization of a giant planet orbiting the young Sun-like star Kepler-63 (KOI-63, , K, $M_\star = 0.98\, M…

Investigation of systematic effects in Kepler data: Seasonal variations in the light curve of HAT-P-7b

V. Van Eylen, M. Lindholm Nielsen, B. Hinrup +2

With years of Kepler data currently available, it can now be attempted to measure variations in planetary transit depths over time. To do so, it is of primary importance to underst…

High angular resolution imaging and infrared spectroscopy of CoRoT candidates

E. W. Guenther, M. Fridlund, R. Alonso +16

Studies of transiting extrasolar planets are of key importance for understanding the nature of planets outside our solar system because their masses, diameters, and bulk densities…

High-precision photometry by telescope defocussing. V. WASP-15 and WASP-16

J. Southworth, L. Mancini, P. Browne +40

We present new photometric observations of WASP-15 and WASP-16, two transiting extrasolar planetary systems with measured orbital obliquities but without photometric follow-up sinc…

Physical properties, transmission and emission spectra of the WASP-19 planetary system from multi-colour photometry

L. Mancini, S. Ciceri, G. Chen +43

We present new ground-based, multi-colour, broad-band photometric measurements of the physical parameters, transmission and emission spectra of the transiting extrasolar planet WAS…

A sub-Mercury-sized exoplanet

Thomas Barclay, Jason F. Rowe, Jack J. Lissauer +55

Since the discovery of the first exoplanet we have known that other planetary systems can look quite unlike our own. However, until recently we have only been able to probe the upp…

Kepler-77b: a very low albedo, Saturn-mass transiting planet around a metal-rich solar-like star

D. Gandolfi, H. Parviainen, M. Fridlund +18

We report the discovery of Kepler-77b (alias KOI-127.01), a Saturn-mass transiting planet in a 3.6-day orbit around a metal-rich solar-like star. We combined the publicly available…

Kepler-62: A five-planet system with planets of 1.4 and 1.6 Earth radii in the Habitable Zone

W. J. Borucki, E. Agol, F. Fressin +62

We present the detection of five planets -- Kepler-62b, c, d, e, and f -- of size 1.31, 0.54, 1.95, 1.61 and 1.41 Earth radii, orbiting a K2V star at periods of 5.7, 12.4, 18.2, 12…

A Giant Planet beyond the Snow Line in Microlensing Event OGLE-2011-BLG-0251

N. Kains, R. Street, J. -Y. Choi +128

We present the analysis of the gravitational microlensing event OGLE-2011-BLG-0251. This anomalous event was observed by several survey and follow-up collaborations conducting micr…

Asteroseismic determination of obliquities of the exoplanet systems Kepler-50 and Kepler-65

W. J. Chaplin, R. Sanchis-Ojeda, T. L. Campante +26

Results on the obliquity of exoplanet host stars -- the angle between the stellar spin axis and the planetary orbital axis -- provide important diagnostic information for theories…

Kepler-68: Three Planets, One With a Density Between That of Earth and Ice Giants

Ronald L. Gilliland, Geoffrey W. Marcy, Jason F. Rowe +30

NASA's Kepler Mission has revealed two transiting planets orbiting Kepler-68. Follow-up Doppler measurements have established the mass of the innermost planet and revealed a third…
