Something new under the Sun: A magnetically driven CH/CN anti-correlation
Y. Momany, L. Monaco, S. Villanova +11
Spectroscopic monitoring surveys have shown that the magnetic cycle alters the photospheric structure of the Sun, perturbing the formation of molecular lines. In parallel, the stud…
PARSEC V2.0: Rotating tracks and isochrones for seven addtional metallicities in the range Z=0.0001-0.03
C. T. Nguyen, G. Costa, A. Bressan +10
PARSEC v2.0 rotating stellar tracks were previously presented for six values of metallicity from subsolar to solar values, with initial rotation rates (, defined as t…
Enhanced Mass Loss of Very Massive Stars: Impact on the Evolution, Binary Processes, and Remnant Mass Spectrum
Kendall G. Shepherd, Guglielmo Costa, Cristiano Ugolini +7
Very massive stars (VMS) play a fundamental role in astrophysics due to their winds and supernovae (SN), and their role as massive black hole (BH) progenitors. However, their origi…
Strikingly high fraction of fast rotators in Magellanic Cloud star clusters
Greta Ettorre, Alessandro Mazzi, Leo Girardi +14
There has been growing evidence that the rich star clusters in the Magellanic Clouds contain significant fractions of rapidly rotating stars. In this work, we aim to constrain thes…
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…
AESOPUS 2.1: Low-Temperature Opacities Extended to High Pressure
Paola Marigo, Francesco Addari, Diego Bossini +5
We address the critical need for accurate Rosseland mean gas opacities in high-pressure environments, spanning temperatures from 100 K to 32000 K. Current opacity tables from Wichi…
The Impact of the Third Dredge-up and Mass Loss in Shaping the Initial-Final Mass Relation of White Dwarfs
Francesco Addari, Paola Marigo, Alessandro Bressan +3
The initial-final mass relation (IFMR) plays a crucial role in understanding stellar structure and evolution by linking a star's initial mass to the mass of the resulting white dwa…
The detection and characterization of highly magnified stars with JWST: Prospects of finding Population III
Erik Zackrisson, Adam Hultquist, Aron Kordt +10
Gravitational lensing may render individual high-mass stars detectable out to cosmological distances, and several extremely magnified stars have in recent years been detected out t…
A Study of Primordial Very Massive Star Evolution. II. Stellar Rotation and Gamma-Ray Burst Progenitors
Guglielmo Volpato, Paola Marigo, Guglielmo Costa +4
We calculate new evolutionary models of rotating primordial very massive stars, with initial mass from to , for two values of the initial metallici…
A Study of Primordial Very Massive Star Evolution
Guglielmo Volpato, Paola Marigo, Guglielmo Costa +3
We present new evolutionary models of primordial very massive stars, with initial masses ranging from to , that extend from…
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…
