A Method to Derive the Absolute Composition of the Sun, the Solar System and the Stars
L. Piersanti, O. Straniero, S. Cristallo
The knowledge of isotopic and elemental abundances of the pristine solar system material provides a fundamental test of galactic chemical evolution models, while the composition of…
Short-lived isotopes and 23Na production in low mass AGB Stars
S. Cristallo, R. Gallino, O. Straniero +2
We discuss the synthesis of some short-lived isotopes and of 23Na in thermally pulsing AGB stars with initial mass of 2 Msun and two different metallicities (Z=1.5e-2, correspondin…
Carbon-Oxygen White Dwarfs Accreting CO-Rich Matter I: A Comparison Between Rotating and Non-Rotating Models
Luciano Piersanti, Simona Gagliardi, Icko Iben +1
We investigate the lifting effect of rotation on the thermal evolution of CO WDs accreting CO-rich matter. We find that rotation induces the cooling of the accreting star so that t…
The chemical composition of White Dwarfs as a test of convective efficiency during core He-burning
Oscar Straniero, Inma Dominguez, Gianluca Imbriani +1
Pulsating white dwarfs provide constraints to the evolution of progenitor stars. We revise He-burning stellar models, with particular attention to core convection and to its connec…
The Influence of N14(e-,nu)C14(alpha,gamma)O18 reaction on the He-Ignition in Degenerate Physical Conditions
Luciano Piersanti, Santi Cassisi, Amedeo Tornambe'
The importance of NCO chain on the onset of the He-flash in degenerate physical conditions has been reevaluated. We find that low-mass, metal-rich (Z 0.001) structures climbi…
Intermediate-mass star models with different helium and metal contents
G. Bono, F. Caputo, S. Cassisi +3
We present a comprehensive theoretical investigation of the evolutionary properties of intermediate-mass stars. The evolutionary sequences were computed from the Zero Age Main Sequ…
The role of NCO reaction chain on the He ignition in degenerate stellar structures
L. Piersanti, S. Cassisi, A. Tornambe'
The role played by NCO reaction in the onset of the He flash in the He core of a RGB star and in low mass CO WDs accreting H/He rich matter is investigated.
Hydrogen-Accreting Carbon-Oxygen White Dwarfs of Low Mass: Thermal and Chemical Behavior of Burning Shells
L. Piersanti, S. Cassisi, I. Iben +1
Numerical experiments have been performed to investigate the thermal behavior of a cooled down white dwarf of initial mass $M_{\rm WD} = 0.516 M_{\sun}$ which accretes hydrogen-ric…
On the very long term evolutionary behavior of hydrogen-accreting Low-Mass CO white dwarfs
L. Piersanti, S. Cassisi, I. Iben +1
Hydrogen-rich matter has been added to a CO white dwarf of initial mass 0.516 \msun at the rates and \msun \yrm1, and results are compared with those fo…
