Rotational radial shear in the low solar photosphere. Direct detection from high-resolution spectro-imaging
T. Corbard, M. Faurobert, B. Gelly +2
Radial differential rotation is an important factor in stellar dynamo theory. In the Sun, helioseismology has revealed a near surface shear layer in the upper 5 to 10% of the conve…

Discontinuous Galerkin finite element method for the continuum radiative transfer problem inside axis-symmetric circumstellar envelopes
J. Perdigon, M. Faurobert, G. Niccolini
The study of the continuum radiative transfer problem inside circumstellar envelopes is both a theoretical and numerical challenge, especially in the frequency-dependent and multi-…
