Thermonuclear oubursts of AM CVn stars
L. R. Yungelson, L. Piersanti, A. Tornambé +1
We consider initial stage of the evolution of AM CVn type stars with white dwarf donors, which is accompanied by thermonuclear explosions in the layer of accreted He. It is shown t…
He-accreting WD: Nucleosynthesis in the extreme binary system (1.02+0.30) M
L. Piersanti, L. R. Yungelson, S. Cristallo +1
We investigate the evolutionary properties of AM~CVn stars with massive white dwarf donors and accretors. As a representative of them we consider a binary initially composed by a 0…
Observational Properties of SNe Ia Progenitors Close to the Explosion
Amedeo Tornambe', Luciano Piersanti, Gabriella Raimondo +1
We determine the expected signal in various observational bands of Supernovae Ia progenitors just before the explosion by assuming the rotating Double Degenerate scenario. Our resu…
Type Ia Supernovae keep memory of their progenitor metallicity
Luciano Piersanti, Eduardo Bravo, Sergio Cristallo +4
The ultimate understanding of Type Ia Supernovae diversity is one of the most urgent issues to exploit thermonuclear explosions of accreted White Dwarfs (WDs) as cosmological yards…
He-Accreting WDs: AM CVn stars with WD Donors
Luciano Piersanti, Lev R. Yungelson, Amedeo Tornambe'
We study the physical and evolutionary properties of the "WD family" of AM CVn stars by computing realistic models of IDD systems. We evaluate self-consistently both the mass trans…
He-Accreting WDs: accretion regimes and final outcomes
L. Piersanti, A. Tornambé, L. R. Yungelson
The behaviour of carbon-oxygen white dwarfs (WDs) subject to direct helium accretion is extensively studied. We aim to analyze the thermal response of the accreting WD to mass depo…
