On the mass and metallicity distribution of parent AGB stars of presolar SiC
Sergio Cristallo, Ambra Nanni, Gabriele Cescutti +5
The vast majority (>=90%) of presolar SiC grains identified in primitive meteorites are relics of ancient asymptotic giant branch (AGB) stars, whose ejecta were incorporated into t…
Constraining the thermally pulsing asymptotic giant branch phase with resolved stellar populations in the Large Magellanic Cloud
Giada Pastorelli, Paola Marigo, Léo Girardi +18
Reliable models of the thermally pulsing asymptotic giant branch (TP-AGB) phase are of critical importance across astrophysics, including our interpretation of the spectral energy…
The mass-loss, expansion velocities and dust production rates of carbon stars in the Magellanic Clouds
Ambra Nanni, Martin A. T. Groenewegen, Bernhard Aringer +5
The properties of carbon stars in the Magellanic Clouds (MCs) and their total dust production rates are predicted by fitting their spectral energy distributions (SED) over pre-comp…
Carbon stars with increased oxygen and nitrogen abundances: hydrostatic dust-free model atmospheres
Bernhard Aringer, Paola Marigo, Walter Nowotny +3
We have computed a grid of hydrostatic spherical COMARCS models for C stars covering metallicities from [Z/H]=0 to -2 and values of the carbon excess [C-O] from 6.41 to 9.15, plus…
Constraining the thermally-pulsing asymptotic giant branch phase with resolved stellar populations in the Small Magellanic Cloud
Giada Pastorelli, Paola Marigo, Léo Girardi +17
The thermally-pulsing asymptotic giant branch (TP-AGB) experienced by low- and intermediate-mass stars is one of the most uncertain phases of stellar evolution and the models need…
Optical properties of amorphous carbon dust around C-stars: new constraints from 2MASS and Gaia observations
Ambra Nanni
In this work the optical properties of amorphous carbon (amC) dust condensed around carbon(C)-stars are constrained by comparing the observations for the Large Magellanic Cloud C-s…
