RR Lyrae From Binary Evolution: Abundant, Young and Metal-Rich
Alexey Bobrick, Giuliano Iorio, Vasily Belokurov +3
RR Lyrae are a well-known class of pulsating horizontal branch stars widely used as tracers of old, metal-poor stellar populations. However, mounting observational evidence shows t…
Gravitational background from dynamical binaries and detectability with 2G detectors
Carole Périgois, Filippo Santoliquido, Yann Bouffanais +5
We study the impact of young clusters on the gravitational wave background from compact binary coalescence. We simulate a catalog of sources from population I/II isolated binary st…
Modeling the outcome of supernova explosions in binary population synthesis using the stellar compactness
Maciej Dabrowny, Nicola Giacobbo, Davide Gerosa
Following the collapse of their cores, some of the massive binary stars that populate our Universe are expected to form merging binaries composed of black holes and neutron stars.…
Dynamics of binary black holes in low-mass young star clusters
Sara Rastello, Michela Mapelli, Ugo N. di Carlo +5
Young star clusters are dynamically active stellar systems and are a common birthplace for massive stars. Low-mass star clusters ( M) are more numerous than…
Intermediate mass black holes from stellar mergers in young star clusters
Ugo N. Di Carlo, Michela Mapelli, Mario Pasquato +8
Intermediate mass black holes (IMBHs) in the mass range bridge the gap between stellar black holes (BHs) and supermassive BHs. Here, we investigate…
The impact of binaries on the evolution of star clusters from turbulent molecular clouds
Stefano Torniamenti, Alessandro Ballone, Michela Mapelli +5
Most of massive stars form in binary or higher-order systems in clumpy, sub-structured clusters. In the very first phases of their life, these stars are expected to interact with t…
High mass but low spin: an exclusion region to rule out hierarchical black-hole mergers as a mechanism to populate the pair-instability mass gap
Davide Gerosa, Nicola Giacobbo, Alberto Vecchio
The occurrence of pair-instability supernovae is predicted to prevent the formation of black holes with masses . Recent gravitational-wave detections in this ma…

Michela Mapelli, Marco Dall'Amico, Yann Bouffanais +8
We explore hierarchical black hole (BH) mergers in nuclear star clusters (NSCs), globular clusters (GCs) and young star clusters (YSCs), accounting for both original and dynamicall…
New insights on binary black hole formation channels after GWTC-2: young star clusters versus isolated binaries
Yann Bouffanais, Michela Mapelli, Filippo Santoliquido +5
With the recent release of the second gravitational-wave transient catalogue (GWTC-2), which introduced dozens of new detections, we are at a turning point of gravitational wave as…
Constraining accretion efficiency in massive binary stars with LIGO-Virgo black holes
Yann Bouffanais, Michela Mapelli, Filippo Santoliquido +3
The growing sample of LIGO--Virgo black holes (BHs) opens new perspectives for the study of massive binary evolution. Here, we study the impact of mass accretion efficiency and com…
