The Core Mass Growth and Stellar Lifetime of Thermally Pulsing Asymptotic Giant Branch Stars
Jason S. Kalirai, Paola Marigo, Pier-Emmanuel Tremblay
We establish new constraints on the intermediate-mass range of the initial-final mass relation by studying white dwarfs in four young star clusters, and apply the results to study…
Evolution of Thermally Pulsing Asymptotic Giant Branch Stars III. Dust production at supersolar metallicities
Ambra Nanni, Alessandro Bressan, Paola Marigo +1
We extend the formalism presented in our recent calculations of dust ejecta from the Thermally Pulsing Asymptotic Giant Branch (TP-AGB) phase, to the case of super-solar metallicit…
The insidious boosting of TP-AGB stars in intermediate-age Magellanic Cloud clusters
Leo Girardi, Paola Marigo, Alessandro Bressan +1
(Abridged) In the recent controversy about the role of TP-AGB stars in evolutionary population synthesis (EPS) models of galaxies, one particular aspect is puzzling: TP-AGB models…
Evolution of Thermally Pulsing Asymptotic Giant Branch Stars II. Dust production at varying metallicity
Ambra Nanni, Alessandro Bressan, Paola Marigo +1
We present the dust ejecta of the new stellar models for the Thermally Pulsing Asymptotic Giant Branch (TP-AGB) phase computed with the COLIBRI code. We use a formalism of dust gro…
Evolution of Thermally Pulsing Asymptotic Giant Branch Stars I. The COLIBRI Code
Paola Marigo, Alessandro Bressan, Ambra Nanni +2
We present the COLIBRI code for computing the evolution of stars along the TP-AGB phase. Compared to purely synthetic TP-AGB codes, COLIBRI relaxes a significant part of their anal…
An extended main sequence turn-off in the Small Magellanic Cloud star cluster NGC411
Leo Girardi, Paul Goudfrooij, Jason S. Kalirai +8
Based on new observations with the Wide Field Camera 3 onboard the Hubble Space Telescope, we report the discovery of an extended main sequence turn-off (eMSTO) in the intermediate…
