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…
Recent advances in the theoretical modeling of pulsating low-mass He-core white dwarfs
A. H. Córsico, L. G. Althaus, L. M. Calcaferro +3
Many extremely low-mass (ELM) white-dwarf (WD) stars are currently being found in the field of the Milky Way. Some of these stars exhibit long-period nonradial -mode pulsations,…
Pulsating low-mass white dwarfs in the frame of new evolutionary sequences: III. The pre-ELM white dwarf instability strip
A. H. Córsico, L. G. Althaus, A. M. Serenelli +3
Two low-mass pre-white dwarfs, which could be precursors of ELM white dwarfs, have been observed to show multiperiodic photometric variations. They could constitute a new class of…
