The transition from carbon dust to silicates production in low-metallicity AGB and SAGB stars
P. Ventura, M. Di Criscienzo, R. Schneider +6
We compute the mass and composition of dust produced by stars with masses in the range 1Msun<M<8 Msun and with a metallicity of Z=0.001 during their AGB and Super AGB phases. Stell…
The first low-mass stars: critical metallicity or dust-to-gas ratio?
Raffaella Schneider, Kazuyuki Omukai, Simone Bianchi +1
We explore the minimal conditions which enable the formation of metal-enriched solar and sub-solar mass stars. We find that in the absence of dust grains, gas fragmentation occurs…
The origin of dust in high redshift QSOs: the case of SDSS J1148+5251
Rosa Valiante, Raffaella Schneider, Stefania Salvadori +1
We present a semi-analytical model for the formation and evolution of a high redshift quasar (QSO). We reconstruct a set of hierarchical merger histories of a 10^13 Msun dark matte…
