Kepler Observations of the Asteroseismic Binary HD 176465
T. R. White, O. Benomar, V. Silva Aguirre +31
Binary star systems are important for understanding stellar structure and evolution, and are especially useful when oscillations can be detected and analysed with asteroseismology.…
Detection of Solar-Like Oscillations, Observational Constraints, and Stellar Models for Cyg, the Brightest Star Observed by the {\it Kepler} Mission
J. A. Guzik, G. Houdek, W. J. Chaplin +52
Cygni is an F3 spectral-type main-sequence star with visual magnitude V=4.48. This star was the brightest star observed by the original Kepler spacecraft mission. Short-cadence…
Asteroseismology of solar-type stars with K2
W. J. Chaplin, M. N. Lund, R. Handberg +44
We present the first detections by the NASA K2 Mission of oscillations in solar-type stars, using short-cadence data collected during K2 Campaign\,1 (C1). We understand the asteros…
Ages and fundamental properties of Kepler exoplanet host stars from asteroseismology
V. Silva Aguirre, G. R. Davies, S. Basu +21
We present a study of 33 {\it Kepler} planet-candidate host stars for which asteroseismic observations have sufficiently high signal-to-noise ratio to allow extraction of individua…
Asteroseismic stellar activity relations
A. Bonanno, E. Corsaro, C. Karoff
In asteroseismology an important diagnostic of the evolutionary status of a star is the small frequency separation which is sensitive to the gradient of the mean molecular weight i…
Sounding stellar cycles with Kepler - II. Ground-based observations
C. Karoff, T. S. Metcalfe, W. J. Chaplin +11
We have monitored 20 Sun-like stars in the Kepler field-of-view for excess flux with the FIES spectrograph on the Nordic Optical Telescope since the launch of Kepler spacecraft in…
Atmospheric parameters of 82 red giants in the Kepler field
A. O. Thygesen, S. Frandsen, H. Bruntt +10
Context: Accurate fundamental parameters of stars are essential for the asteroseismic analysis of data from the NASA Kepler mission. Aims: We aim at determining accurate atmospheri…
Verification of the Kepler Input Catalog from Asteroseismology of Solar-type Stars
G. A. Verner, W. J. Chaplin, S. Basu +25
We calculate precise stellar radii and surface gravities from the asteroseismic analysis of over 500 solar-type pulsating stars observed by the Kepler space telescope. These physic…
Asteroseismology of Solar-type stars with Kepler II: Stellar Modeling
T. S. Metcalfe, M. J. P. F. G. Monteiro, M. J. Thompson +9
Observations from the Kepler satellite were recently published for three bright G-type stars, which were monitored during the first 33.5d of science operations. One of these stars,…
Modelling the Autocovariance of the Power Spectrum of a Solar-Type Oscillator
T. L. Campante, C. Karoff, W. J. Chaplin +3
Asteroseismology is able to conduct studies on the interiors of solar-type stars from the analysis of stellar acoustic spectra. However, such an analysis process often has to rely…
Asteroseismology of Solar-type stars with Kepler III. Ground-based Data
Joanna Molenda-Zakowicz, Hans Bruntt, Sergio Sousa +15
We report on the ground-based follow-up program of spectroscopic and photometric observations of solar-like asteroseismic targets for the Kepler space mission. These stars constitu…
Asteroseismology of Solar-type Stars with Kepler I: Data Analysis
C. Karoff, W. J. Chaplin, T. Appourchaux +46
We report on the first asteroseismic analysis of solar-type stars observed by Kepler. Observations of three G-type stars, made at one-minute cadence during the first 33.5d of scien…
The solar-like CoRoT target HD 170987: spectroscopic and seismic observations
S. Mathur, R. A. Garcia, C. Catala +22
The CoRoT mission is in its third year of observation and the data from the second long run in the galactic centre direction are being analysed. The solar-like oscillating stars th…
