Chemical evolution and abundance gradients in the Milky Way
Andreu Alibes, Javier Labay, Ramon Canal
We extend our model of chemical evolution that successfully account for the main observables in the solar neighborhood (Alibes, Labay & Canal 2001) to the whole Milky Way halo and…
The cosmic rate of supernovae and the range of stars ending as Type Ia SNe
P. Ruiz-Lapuente, R. Canal
The present cosmic rate of Type Ia supernovae (SNeIa) suggests that about 6% of all stars in binary systems with primaries in the initial mass range $3-9\ M\sun$ end up as SNeIa. I…
Light Element Evolution in the Galactic Halo
Andreu Alibes, Ramon Canal
Using a time-dependent Galactic Cosmic Ray flux proportional to the halo Star Formation Rate and including astration and neutrino-induced nucleosynthesis, we have studied the evolu…
Light-Element Nucleosynthesis: Big Bang and Later on
J. Lopez-Suarez, R. Canal
We present a model for big bang nucleosynthesis which combines baryon inhomogeneities with the effects of the decays of massive particles (masses higher than a few GeV). Those part…
SNeIa: on the binary progenitors and expected statistics
P. Ruiz-Lapuente, R. Canal, A. Burkert
A review of type Ia supernovae (SNe Ia) statistics as expected from the different scenarios and explosion models so far suggested is presented.
