Asteroseismic inference on rotation, gyrochronology and planetary system dynamics of 16 Cygni
G. R. Davies, W. J. Chaplin, W. M. Farr +13
The solar analogs 16 Cyg A and 16 Cyg B are excellent asteroseismic targets in the \Kepler field of view and together with a red dwarf and a Jovian planet form an interesting syste…
Kepler-432: a red giant interacting with one of its two long period giant planets
Samuel N. Quinn, Timothy R. White, David W. Latham +28
We report the discovery of Kepler-432b, a giant planet () transiting an evolved star $(M_\star =…
Super-Nyquist asteroseismology of solar-like oscillators with Kepler and K2 - expanding the asteroseismic cohort at the base of the red-giant branch
W. J. Chaplin, Y. Elsworth, G. R. Davies +4
We consider the prospects for detecting solar-like oscillations in the "super-Nyquist" regime of long-cadence (LC) Kepler photometry, i.e., above the associated Nyquist frequency o…
Why should we correct reported pulsation frequencies for stellar line-of-sight Doppler velocity shifts?
G. R. Davies, R. Handberg, A. Miglio +3
In the age of Kepler and Corot, extended observations have provided estimates of stellar pulsation frequencies that have achieved new levels of precision, regularly exceeding fract…
Determining stellar macroturbulence using asteroseismic rotational velocities from Kepler
Amanda P. Doyle, Guy R. Davies, Barry Smalley +2
The Rossiter-McLaughlin effect observed for transiting exoplanets often requires prior knowledge of the stellar projected equatorial rotational velocity. This is usually provided b…
Asteroseismic inference on the spin-orbit misalignment and stellar parameters of HAT-P-7
Mikkel N. Lund, Mia Lundkvist, Victor Silva Aguirre +12
The measurement of obliquities in star-planet systems is of great importance for the understanding of planet system formation and evolution. The bright and well studied HAT-P-7 sys…
Kepler-93b: A Terrestrial World Measured to within 120 km, and a Test Case for a New Spitzer Observing Mode
Sarah Ballard, William J. Chaplin, David Charbonneau +22
We present the characterization of the Kepler-93 exoplanetary system, based on three years of photometry gathered by the Kepler spacecraft. The duration and cadence of the Kepler o…
BiSON data preparation: A correction for differential extinction and the weighted averaging of contemporaneous data
G. R. Davies, W. J. Chaplin, Y. Elsworth +1
The Birmingham Solar Oscillations Network (BiSON) has provided high-quality high-cadence observations from as far back in time as 1978. These data must be calibrated from the raw o…
Oscillation mode linewidths and heights of 23 main-sequence stars observed by Kepler
T. Appourchaux, H. M. Antia, O. Benomar +9
Solar-like oscillations have been observed by Kepler and CoRoT in many solar-type stars, thereby providing a way to probe the stars using asteroseismology. We provide the mode line…
Rotation and magnetism of Kepler pulsating solar-like stars. Towards asteroseismically calibrated age-rotation relations
R. A. Garcia, T. Ceillier, D. Salabert +16
Kepler ultra-high precision photometry of long and continuous observations provides a unique dataset in which surface rotation and variability can be studied for thousands of stars…
Limits on surface gravities of Kepler planet-candidate host stars from non-detection of solar-like oscillations
T. L. Campante, W. J. Chaplin, M. N. Lund +20
We present a novel method for estimating lower-limit surface gravities log g of Kepler targets whose data do not allow the detection of solar-like oscillations. The method is teste…
Masses, Radii, and Orbits of Small Kepler Planets: The Transition from Gaseous to Rocky Planets
Geoffrey W. Marcy, Howard Isaacson, Andrew W. Howard +100
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…
Seismic constraints on the radial dependence of the internal rotation profiles of six Kepler subgiants and young red giants
S. Deheuvels, G. Doğan, M. J. Goupil +25
Context : We still do not know which mechanisms are responsible for the transport of angular momentum inside stars. The recent detection of mixed modes that contain the signature o…
