AGB stars in the LMC: evolution of dust in circumstellar envelopes
F. Dell'Agli, P. Ventura, R. Schneider +4
We calculated theoretical evolutionary sequences of asymptotic giant branch (AGB) stars, including formation and evolution of dust grains in their circumstellar envelope. By consid…
Supernova dust formation and the grain growth in the early universe: The critical metallicity for low-mass star formation
Gen Chiaki, Stefania Marassi, Takaya Nozawa +5
We investigate the condition for the formation of low-mass second-generation stars in the early universe. It has been proposed that gas cooling by dust thermal emission can trigger…
High-redshift quasars host galaxies: is there a stellar mass crisis?
Rosa Valiante, Raffaella Schneider, Stefania Salvadori +1
We investigate the evolutionary properties of a sample of quasars at 5<z<6.4 using the semi-analytical hierarchical model GAMETE/QSOdust. We find that the observed properties of th…
The dust production rate of AGB stars in the Magellanic Clouds
Raffaella Schneider, Rosa Valiante, Paolo Ventura +4
We compare theoretical dust yields for stars with mass 1 Msun < mstar < 8 Msun, and metallicities 0.001 < Z < 0.008 with observed dust production rates (DPR) by carbon- rich and ox…
On the alumina dust production in the winds of O-rich Asymptotic Giant Branch stars
F. Dell'Agli, D. A. García-Hernández, C. Rossi +3
The O-rich Asymptotic Giant Branch (AGB) stars experience strong mass loss with efficient dust condensation and they are major sources of dust in the interstellar medium. Alumina d…
Dissecting the Spitzer color-magnitude diagrams of extreme LMC AGB stars
F. Dell'Agli, P. Ventura, D. A. García Hernández +5
We trace the full evolution of low- and intermediate-mass stars () during the Asymptotic Giant Branch (AGB) phase in the {\it Spitzer} two-color…
