Chemical yields from low- and intermediate-mass stars
Paola Marigo
We present new sets of chemical yields from low- and intermediate-mass stars with 0.8 Msun <= M <= Mup ~ 5 Msun, and three choices of the metallicity, Z=0.02, Z=0.008, and Z=0.004…
Evolutionary models of zero metallicity stars
Paola Marigo, Cesare Chiosi, Leo Girardi +1
We present new evolutionary models for zero-metallicity stars, covering a large range of initial masses (from 0.8 to 100 M_sun). Models are computed with overshooting from stellar…
Is the core mass-luminosity relation violated by the occurrence of the third dredge-up ?
P. Marigo, L. Girardi, A. Weiss +1
The core mass-luminosity (Mc-L) relation of TP-AGB stars is a key ingredient in synthetic calculations of their evolution. Recently, Herwig et al. (1998) have presented full calcul…
The third dredge-up and the carbon star luminosity functions in the Magellanic Clouds
Paola Marigo, Leo Girardi, Alessandro Bressan
We investigate the formation of carbon stars as a function of the stellar mass and parent metallicity. Theoretical modelling is based on an improved scheme for treating the third d…
