M2 internship and PhD funding in astrophysical fluid mechanics is available at LJAD, in collaboration with Observatoire de la Côte d'Azur. The project will focus on the numerical modeling of the nonlinear magnetohydrodynamic instabilities giving rise to magnetism in the radiative layers of solar-type stars. Understanding subcritical dynamo instability in these layers is instrumental for stellar evolution models, particularly stellar rotation dynamics. Indeed, currently available theoretical predictions are largely incompatible with observational data recently obtained through NASA's Kepler space mission. An aspect of the project will also focus on characterizing the observable consequences, and more specifically the signature of magnetic fields on asteroseismic signals. The project will thus be part of the exploitation of the European space mission PLATO (ESA), in which the Observatoire de la Côte d'Azur is involved.
