Analysing solar-like oscillations with an automatic pipeline
S. Mathur, R. A. Garcia, C. Regulo +3
Kepler mission will provide a huge amount of asteroseismic data during the next few years, among which hundreds of solar-like stars will be targeted. The amount of stars and their…
Solar-like oscillations with low amplitude in the CoRoT target HD 181906
R. A. Garcia, C. Regulo, R. Samadi +23
Context: The F8 star HD 181906 (effective temperature ~6300K) was observed for 156 days by the CoRoT satellite during the first long run in the centre direction. Analysis of the da…
Wreathes of Magnetism in Rapidly Rotating Suns
Benjamin P. Brown, Matthew K. Browning, Mark S. Miesch +2
When our Sun was young it rotated much more rapidly than now. Observations of young, rapidly rotating stars indicate that many possess substantial magnetic activity and strong axis…
Radius determination of solar-type stars using asteroseismology: What to expect from the Kepler mission
D. Stello, W. J. Chaplin, H. Bruntt +22
For distant stars, as observed by the NASA Kepler satellite, parallax information is currently of fairly low quality and is not complete. This limits the precision with which the a…
Galactic Globular and Open Clusters in the Sloan Digital Sky Survey. II. Test of Theoretical Stellar Isochrones
Deokkeun An, Marc H. Pinsonneault, Thomas Masseron +6
We perform an extensive test of theoretical stellar models for main-sequence stars in ugriz, using cluster fiducial sequences obtained in the previous paper of this series. We gene…
2D numerical study of the radiation influence on shock structure relevant to laboratory astrophysics
Matthias González, Edouard Audit, Chantal Stehlé
Radiative shocks are found in various astrophysical objects and particularly at different stages of stellar evolution. Studying radiative shocks, their topology, and thermodynamica…
