Hubble Space Telescope survey of Magellanic Cloud star clusters. Photometry and astrometry of 113 clusters and early results
A. P. Milone, G. Cordoni, A. F. Marino +29
In the past years, we have undertaken an extensive investigation of LMC and SMC star clusters based on HST data. We present photometry and astrometry of stars in 101 fields observe…
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…
Compact object mergers: exploring uncertainties from stellar and binary evolution with SEVN
Giuliano Iorio, Michela Mapelli, Guglielmo Costa +9
Population-synthesis codes are an unique tool to explore the parameter space of massive binary star evolution and binary compact object (BCO) formation. Most population-synthesis c…
Simulating the Legacy Survey of Space and Time stellar content with TRILEGAL
Piero Dal Tio, Giada Pastorelli, Alessandro Mazzi +19
We describe a large simulation of the stars to be observed by the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST). The simulation is based on the TRILEGAL code, wh…
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…
Formation of black holes in the pair-instability mass gap: Hydrodynamical simulations of a head-on massive star collision
Alessandro Ballone, Guglielmo Costa, Michela Mapelli +3
The detection of the binary black hole merger GW190521, with primary black hole mass , proved the existence of black holes in the theoretically pr…
Formation of black holes in the pair-instability mass gap: evolution of a post-collision star
Guglielmo Costa, Alessandro Ballone, Michela Mapelli +1
The detection of GW190521 by the LIGO-Virgo collaboration has revealed the existence of black holes (BHs) in the pair-instability (PI) mass gap. Here, we investigate the formation…
