Influence of thermohaline convection on diffusion-induced iron accumulation in A stars (2009)

Théado, Sylvie, Vauclair, Sylvie, Alecian, Georges, LeBlanc, Francis

Atomic diffusion may lead to heavy element accumulation inside stars in certain specific layers. Iron accumulation in the Z-bump opacity region has been invoked by several authors to quantitatively...

Time-dependent diffusion in A-stars (1998)

Alecian, Georges

Each time diffusion of elements is invoked in explaining abundance anomalies in a star, this supposes implicitly that a stratification process is in progress somewhere in that star. This means also,...
