Relationship between low and high frequencies in Delta Scuti stars: Photometric Kepler and spectroscopic analyses of the rapid rotator KIC 8054146
M. Breger, L. Fossati, L. Balona +9
Two years of Kepler data of KIC 8054146 (delta Sct/gamma Dor hybrid) revealed 349 statistically significant frequencies between 0.54 and 191.36 c/d (6.3 microHz to 2.21 mHz). The 1…
Kepler-47: A Transiting Circumbinary Multi-Planet System
Jerome A. Orosz, William F. Welsh, Joshua A. Carter +36
We report the detection of Kepler-47, a system consisting of two planets orbiting around an eclipsing pair of stars. The inner and outer planets have radii 3.0 and 4.6 times that o…
The Neptune-Sized Circumbinary Planet Kepler-38b
Jerome A. Orosz, William F. Welsh, Joshua A. Carter +28
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 ev…
A pulsation zoo in the hot subdwarf B star KIC 10139564 observed by Kepler
A. S. Baran, M. D. Reed, D. Stello +13
We present our analyses of 15 months of Kepler data on KIC 10139564. We detected 57 periodicities with a variety of properties not previously observed all together in one pulsating…
A Class of Eccentric Binaries with Dynamic Tidal Distortions Discovered with Kepler
Susan E. Thompson, Mark Everett, Fergal Mullally +10
We have discovered a class of eccentric binary systems within the Kepler data archive that have dynamic tidal distortions and tidally-induced pulsations. Each has a uniquely shaped…
Oscillation mode linewidths of main-sequence and subgiant stars observed by Kepler
T. Appourchaux, O. Benomar, M. Gruberbauer +20
Solar-like oscillations have been observed by {\it Kepler} and CoRoT in several solar-type stars. We study the variations of stellar p-mode linewidth as a function of effective tem…
