Magnetic confinement of the solar tachocline: II. Coupling to a convection zone
A. Strugarek, A. S. Brun, J. -P. Zahn
The reason for the observed thinness of the solar tachocline is still not well understood. One of the explanations that have been proposed is that a primordial magnetic field rende…
Visibilities and bolometric corrections for stellar oscillation modes observed by Kepler
J. Ballot, C. Barban, C. van 't Veer-Menneret
Kepler produces a large amount of data used for asteroseismological analyses, particularly of solar-like stars and red giants. The mode amplitudes observed in the Kepler spectral b…
The close circumstellar environment of Betelgeuse - II. Diffraction-limited spectro-imaging from 7.76 to 19.50 microns with VLT/VISIR
Pierre Kervella, Guy Perrin, Andrea Chiavassa +4
Context: Mass-loss occurring in red supergiants (RSGs) is a major contributor to the enrichment of the interstellar medium in dust and molecules. The physical mechanism of this mas…
Accurate p-mode measurements of the G0V metal-rich CoRoT target HD 52265
J. Ballot, L. Gizon, R. Samadi +27
The star HD 52265 is a G0V metal-rich exoplanet-host star observed in the seismology field of the CoRoT space telescope from November 2008 to March 2009. The satellite collected 11…
About the p-mode frequency shifts in HD 49933
D. Salabert, C. Regulo, J. Ballot +2
We study the frequency dependence of the frequency shifts of the low-degree p modes measured in the F5V star HD 49933, by analyzing the second run of observations collected by the…
Magnetic Cycles in a Convective Dynamo Simulation of a Young Solar-type Star
Benjamin P. Brown, Mark S. Miesch, Matthew K. Browning +2
Young solar-type stars rotate rapidly and many are magnetically active; some undergo magnetic cycles similar to the 22-year solar activity cycle. We conduct simulations of dynamo a…
