The -processes nucleosynthesis during the formation of He-rich hot-subdwarf stars

T. Battich, M. M. Miller Bertolami, A. Weiss +3

It has been shown that proton ingestion episodes can happen in the formation of hot-subdwarf stars, and that neutron-capture processes are possible in those cases. Moreover, some h…

A self-synthesized origin of heavy metals in hot subdwarf stars?

T. Battich, M. M. Miller Bertolami, A. M. Serenelli +2

Some He-rich hot subdwarf stars (He-sdOBs) present high abundances of trans-iron elements, such as Sr, Y, Zr and Pb. Diffusion processes are important in hot subdwarf stars, and it…

Episodic lithium production by extra-mixing in red giants

P. A. Denissenkov, A. Weiss

The recent discovery of low-mass red giants with enhanced atmospherical Li abundance in galactic low-metallicity stellar clusters adds to the mysterious phenomenon of the Li-rich g…

The puzzling theoretical predictions for the luminosity of clumping He burning stars

V. Castellani, S. Degl'Innocenti, L. Girardi +3

This paper deals with theoretical predictions for He burning models in a range of masses covering the so-called Red Giant Branch phase transition. Taking as a guideline the observa…

The puzzling MgAl anticorrelation in globular-cluster red giants: primordial plus deep mixing scenario?

P. A. Denissenkov, G. S. Da Costa, J. E. Norris +1

Star-to-star abundance variations of C, N, O, Na and Al in globular-cluster red giants have been recently supplemented by the finding that [Mg/Fe] is depleted in stars with extreme…
