The CoRoT target HD175726: an active star with weak solar-like oscillations
B. Mosser,Eric Michel,T. Appourchaux,Caroline Barban,Frédéric Baudin,Patrick Boumier,H. Bruntt,C. Catala,Sébastien Deheuvels,Rafael A. García,Patrick Gaulme,Clara Régulo,Ian W. Roxburgh,R. Samadi,Graham A. Verner,M. Auvergne,A. Baglin,J. Ballot,O. Benomar,Savita Mathur +19 more
TL;DR: In this paper, the authors report observations of the star HD175726 that lasted for 27 days during the first short run of the CoRoT mission, which reveals a high activity signal and the power spectrum presents an excess due to solar-like oscillations with a low signal-to-noise ratio.
Journal ArticleDOI
Absolute dimensions of solar-type eclipsing binaries. II. V636 Centauri: A 1.05 Msun primary with an active, cool, oversize 0.85 Msun secondary
J. V. Clausen,H. Bruntt,A. Claret,A. Larsen,Johannes Andersen,Birgitta Nordström,Alvaro Giménez +6 more
TL;DR: In this paper, the absolute dimensions and abundances for the solar-type detached eclipsing binary V636 Cen were determined based on uv-by light curves, uvby-beta standard photometry, radial velocity observations, and high-resolution spectra.
Journal ArticleDOI
Confirmation of solar-like oscillations in eta Bootis
H. Kjeldsen,Timothy R. Bedding,Ivan K. Baldry,S. Frandsen,H. Bruntt,Frank Grundahl,K. Lang,R. P. Butler,Debra A. Fischer,G. W. Marcy,A. Misch,Steve Vogt +11 more
TL;DR: In this article, the authors report observations of the G0 subgiant eta Boo made in 1998, in Balmer-line equivalent width with the 2.5m Nordic Optical Telescope and in velocity with the 24-inch Lick CAT.
Journal ArticleDOI
Establishing the accuracy of asteroseismic mass and radius estimates of giant stars - I. Three eclipsing systems at [Fe/H] ∼ -0.3 and the need for a large high-precision sample
K. Brogaard,K. Brogaard,Camilla Juul Hansen,Andrea Miglio,Andrea Miglio,D. Slumstrup,S. Frandsen,Jens Jessen-Hansen,Mikkel N. Lund,Mikkel N. Lund,Diego Bossini,A. O. Thygesen,Guy R. Davies,Guy R. Davies,William J. Chaplin,William J. Chaplin,Torben Arentoft,H. Bruntt,Frank Grundahl,Rasmus Handberg +19 more
TL;DR: In this paper, the authors measured the masses, radii, effective temperatures and metallicities of three eclipsing binary stars with a red giant component that displays solar-like oscillations and found that the scaling relations without corrections to Δν systematically overestimate the masses of the three red giants by 11.7, 13.7 and 18.9 percent, respectively.
Journal ArticleDOI

TL;DR: In this article, a short-period binary star system with total eclipses and multi-periodic delta Scuti pulsations was analyzed using the Kepler satellite photometry of KIC 10661783.
