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…

Helioseismic inference of the solar radiative opacity
Gaël Buldgen, Jean-Christophe Pain, Philippe Cossé +18
The Sun is the most studied of all stars, and thus constitutes a benchmark for stellar models. However, our vision of the Sun is still incomplete, as illustrated by the current deb…
