We find that low-degree low-order g-modes become unstable in metal-poor low-mass stars due to the $\varepsilon$-mechanism of the pp-chain. Since the outer convection zone of these stars is limited onl...

In a previous study published in Astrobiology, we focused on the evolution of habitability of a 10 M_E super-Earth planet orbiting a star akin to the Sun. This study was based on a concept of planetar...
Abundance anomalies in pre-main-sequence stars: Stellar evolution models with mass loss

Aims. The effects of atomic diffusion on internal and surface abundances of A and F pre–main-sequence stars with mass loss are studied in order to determine at what age the effects materialize, as wel...
