Expected Changes of Supernovae with Redshift due to Evolution of their Progenitors
Inma Dominguez, Peter Hoeflich, Oscar Straniero +2
We have analyzed the influence of the stellar populations, from which SN progenitors come from, on the observational outcome, including the metal free Pop. III. We use our models t…
s-Process Nucleosynthesis in Carbon Stars
C. Abia, I. Dominguez, R. Gallino +6
We present the first detailed and homogeneous analysis of the s-element content in Galactic carbon stars of N-type. Abundances of Sr,Y, Zr (low-mass s-elements, or ls) and of Ba, L…
The Kr85 s-process Branching and the Mass of Carbon Stars
C. Abia, M. Busso, R. Gallino +3
We present new spectroscopic observations for a sample of C(N)-type red giants. These objects belong to the class of Asymptotic Giant Branch stars, experiencing thermal instabiliti…
Constraints on the Progenitors of SNeIa & Implications for the Cosmological Equation of State
I. Dominguez, P. Hoeflich, O. Straniero
Detailed calculations for the stellar evolution, explosion and light curves have been performed to quantify the influence of the main sequence mass M(MS) and the metallicity of the…
Evolution and Nucleosynthesis of Zero Metal Intermediate Mass Stars
Alessandro Chieffi, Inma Dominguez, Marco Limongi +1
New stellar models with mass ranging between 4 and 8 Mo, Z=0 and Y=0.23 are presented. The models have been evolved from the pre Main Sequence up to the Asymptotic Giant Branch (AG…
The role of Z=0 AGB stars on the early chemical enrichment
Inma Dominguez, Carlos Abia, Oscar Straniero +2
We present theoretical evolutionary models for Z=0 stars in the mass range 4< M/Mo <8 from the pre-main sequence up to the AGB phase. Contrary to previous calculations we found tha…
Extreme Type IIp Supernovae as Yardsticks for Cosmology
P. Höflich, O. Straniero, M. Limongi +2
Evolutionary effects with redshift of core collapse supernovae and their application to cosmology have been studied based on an extensive grid of stellar models between 13 and 25 M…
Do zero metal intermediate mass stars experience thermal pulses?
I. Dominguez, O. Straniero, M. Limongi +1
We have studied the evolution of intermediate mass (M.ge.5Mo) zero metal (Z=0) stars with particular attention to the AGB phase. At variance with previous claims we find that these…
Evolution of Type Ia Supernovae on Cosmological Time Scales
Inma Dominguez, Peter Hoeflich, Oscar Straniero +1
Due to their high luminosity at maximum and degree of homogeneity, Type Ia supernovae have been extensively used for cosmological purpouses, in particular to estimate extragalactic…
