The impact of envelope binding energies on the merger rate density of binary compact objects
Cecilia Sgalletta, Guglielmo Costa, Giuliano Iorio +8
The common envelope (CE) phase plays a key role in the formation of binary compact object systems. Its final outcome strongly depends on the envelope binding energy, but this quant…
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…
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…
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…
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…
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 Fresh Look at AGB stars in Galactic Open Clusters with Gaia: Impact on Stellar Models and the Initial-Final Mass Relation
Paola Marigo, Diego Bossini, Michele Trabucchi +7
Benefiting from the GAIA second and early third releases of photometric and astrometric data we examine the population of asymptotic giant branch (AGB) stars that appear in the fie…
