The Stellar Winds Atlas II: Black Hole Formation at Solar Metallicity
Amedeo Romagnolo, Floor S. Broekgaarden, Alex C. Gormaz-Matamala +7
The paper builds a comprehensive grid of stellar evolution models to compare 14 wind prescriptions and shows that black‑hole masses at solar metallicity are determined by whether a…
A Framework for Linking Pre- and Post-Common Envelope Binary Properties with Star Clusters: The First Demonstration with a Massive White Dwarf+M Dwarf Binary in Alessi 12
Steffani M. Grondin, Maria R. Drout, Jason Nordhaus +12
Common envelope (CE) evolution is a critical phase in the lives of binary stars, producing close binaries that are progenitors of type Ia supernovae and gravitational wave sources.…
Lower Your Rates: On Claims of a Binary Black Hole Merger-Rate Crisis
Floor S. Broekgaarden
Recent studies have argued that isolated binary evolution simulations generically overestimate the observed local binary black hole (BBH) merger rate, even after adopting observati…
How Common Are Common Envelopes? Quantifying Their Role in Forming Gravitational-Wave Sources
Floor S. Broekgaarden, Ana Lam, Sasha Levina +14
A central goal of gravitational-wave astronomy is to use merging binary black hole (BBH), black hole-neutron star (BHNS), and binary neutron star (BNS) systems as fossils to recons…
Massquerade: Impacts of Mass Ratio Reversals on Binary Black Hole Merger Rates and Mass Distributions
Tyler B. Smith, Floor Broekgaarden, Sasha Levina +4
We investigate the role of mass ratio reversal (MRR), in which the initially less massive star in a binary forms the more massive compact object, in shaping the astrophysical binar…
From cosmological simulations to binary black hole mergers: The impact of using analytical star formation history models on gravitational-wave source populations
Sasha Levina, Floor Broekgaarden, Lieke van Son +4
Observations of binary black hole (BBH) mergers provide a unique window into the lives of massive stars across cosmic time. Connecting redshift-dependent merger properties to massi…
