Evolutionary tracks, ejecta, and ionizing photons from intermediate-mass to very massive stars with PARSEC
G. Costa, K. G. Shepherd, A. Bressan +12
Recent advancements in stellar evolution modeling offer unprecedented accuracy in predicting the evolution and deaths of stars. We present new stellar evolutionary models computed…
A combined study of thermohaline mixing and envelope overshooting with PARSEC: Calibration to NGC 6397 and M4
C. T. Nguyen, A. Bressan, A. J. Korn +7
Thermohaline mixing is one of the main processes in low-mass red giant stars that affect the transport of chemicals and, thus, the surface abundances along the evolution. The inter…
New proton-capture rates on carbon isotopes and their impact on the astrophysical ratio
J. Skowronski, A. Boeltzig, G. F. Ciani +43
The ratio is a significant indicator of nucleosynthesis and mixing processes during hydrogen burning in stars. Its value mainly depends on the…
PARSEC V2.0: Stellar tracks and isochrones of low and intermediate mass stars with rotation
C. T. Nguyen, G. Costa, L. Girardi +6
We present a new comprehensive collection of stellar evolutionary tracks and isochrones for rotating low- and intermediate-mass stars assembled with the updated version of PARSEC V…
The impact of very massive stars on the chemical evolution of extremely metal-poor galaxies
S. Goswami, L. Silva, A. Bressan +6
In recent observations of extremely metal-poor low-mass starburst galaxies, almost solar Fe/O ratios are reported, despite N/O ratios consistent with the low metallicity. We invest…
Direct measurement of the 13C(α,n)16O cross section into the s-process Gamow peak
G. F. Ciani, L. Csedreki, D. Rapagnani +45
One of the main neutron sources for the astrophysical s-process is the reaction 13C(α,n)16O, taking place in thermally pulsing Asymptotic Giant Branch stars at temperatures around…
On the effects of the Initial Mass Function on Galactic chemical enrichment
S. Goswami, A. Slemer, P. Marigo +7
There is mounting evidence that the stellar initial mass function (IMF) could extend much beyond the canonical Mi ~100, Msun limit, but the impact of such hypothesis on the chemica…
First star formation with dark matter annihilation
E. Ripamonti, F. Iocco, A. Ferrara +3
We include an energy term based on Dark Matter (DM) self-annihilation during the cooling and subsequent collapse of the metal-free gas, in halos hosting the formation of the first…
Effects of dark matter annihilation on the first stars
F. Iocco, A. Bressan, E. Ripamonti +3
We study the evolution of the first stars in the universe (Population III) from the early pre-Main Sequence until the end of helium burning in the presence of WIMP dark matter anni…
Dark matter annihilation effects on the first stars
F. Iocco, A. Bressan, E. Ripamonti +3
We study the effects of WIMP dark matter (DM) on the collapse and evolution of the first stars in the Universe. Using a stellar evolution code, we follow the pre-Main Sequence (MS)…
Probing AGB nucleosynthesis via accurate Planetary Nebula abundances
P. Marigo, J. Bernard-Salas, S. R. Pottasch +2
The elemental abundances of ten planetary nebulae, derived with high accuracy including ISO and IUE spectra, are analysed with the aid of synthetic evolutionary models for the TP-A…
