Magnetic activity of F stars observed by Kepler
S. Mathur, R. A. Garcia, J. Ballot +6
The study of stellar activity is important because it can provide new constraints for dynamo models, when combined with surface rotation rates and the depth of the convection zone.…
Study of KIC 8561221 observed by Kepler: an early red giant showing depressed dipolar modes
R. A. Garcia, F. Perez Hernandez, O. Benomar +23
The continuous high-precision photometric observations provided by the CoRoT and Kepler space missions have allowed us to better understand the structure and dynamics of red giants…
Investigating magnetic activity of F stars with the it Kepler mission
S. Mathur, R. A. Garcia, J. Ballot +6
The dynamo process is believed to drive the magnetic activity of stars like the Sun that have an outer convection zone. Large spectroscopic surveys showed that there is a relation…
Measuring reliable surface rotation rates from Kepler photometric observations
R. A. Garcia, T. Ceillier, S. Mathur +1
High-quality time series provided by space instrumentation such as CoRoT and Kepler, allow us to measure modulations in the light curves due to changes in the surface of stars rela…
Understanding angular momentum transport in red giants: the case of KIC 7341231
T. Ceillier, P. Eggenberger, R. A. García +1
Context. Thanks to recent asteroseismic observations, it has been possible to infer the radial differential rotation profile of subgiants and red giants. Aims. We want to reproduce…
