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…
