Internal rotation of red giants by asteroseismology
arXiv:1212.4758 · doi:10.1051/epjconf/20134303012
Abstract
We present an asteroseismic approach to study the dynamics of the stellar interior in red-giant stars by asteroseismic inversion of the splittings induced by the stellar rotation on the oscillation frequencies. We show preliminary results obtained for the red giant KIC4448777 observed by the space mission Kepler.
