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…
New evolutionary calculations for the Born Again scenario
M. M. Miller Bertolami, L. G. Althaus, A. M. Serenelli +1
We present evolutionary calculations aimed at describing the born-again scenario for post-AGB remnant stars of 0.5842 and 0.5885 \msun. Results are based on a detailed treatment of…
Evolutionary and pulsational properties of low-mass white dwarf stars with oxygen cores resulting from close binary evolution
L. G. Althaus, A. H. Corsico, A. Gautschy +3
The present work is designed to explore the evolutionary and pulsational properties of low-mass white dwarfs with carbon/oxygen cores. In particular, we follow the evolution of a 0…
