A binary black hole merger rate comparison within the same metallicity-star formation rate framework
Lumen Boco, Michele Bosi, Cecilia Sgalletta +2
Recent studies have suggested that binary population synthesis models, when coupled with observationally based, metallicity-dependent SFRD, overpredict the observed local BBH merge…
The Stellar Winds Atlas II: Black Hole Formation at Solar Metallicity
Amedeo Romagnolo, Floor S. Broekgaarden, Alex C. Gormaz-Matamala +7
Stellar winds are a primary source of uncertainty in predicting the masses of black holes (BHs) from massive stars. At solar metallicity, theoretical models lead to widely divergen…
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…
Can current models predict the local black hole merger rate?
Lumen Boco, Michele Bosi, Cecilia Sgalletta +2
After four observational runs, the Ligo-Virgo-Kagra collaboration estimated a local binary black hole (BBH) merger rate density of $R_{0,\textrm{LVK}}\simeq 14-26\,\textrm{Gpc}^{-3…
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…
The role of accretion efficiency, natal kicks, and angular momentum transport in the formation of the Gaia black holes
Michela Mapelli, Cecilia Sgalletta, Johanna Müller-Horn +5
Gaia has the potential to deliver several tens of new dormant black holes (BHs) with low-mass stellar companions (hereafter, Gaia BHs) in the upcoming fourth data release. Three Ga…
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…
The Stellar Winds Atlas I: Current uncertainties in mass-loss rates
Amedeo Romagnolo, Floor S. Broekgaarden, Konstantinos Antoniadis +1
Stellar winds are a major source of uncertainty in understanding the life and deaths of massive stars. Across studies in the field, prescriptions for stellar winds differ substanti…
StarEstate: A Python Package for Galactic Population Synthesis
Amedeo Romagnolo
I present StarEstate, an open-source Python package for producing rapid, statistically robust galactic population synthesis models. By utilizing optimized pre-calculated inverse-cu…
Development of convective envelopes in massive stars: Implications for gravitational wave sources
Amedeo Romagnolo, Jakub Klencki, Alejandro Vigna-Gomez +1
The structure of stellar envelopes strongly influences the course and outcome of binary mass transfer, in particular of common envelope (CE) evolution. Convective envelopes can mos…
Large Interferometer For Exoplanets (LIFE). XIV. Finding terrestrial protoplanets in the galactic neighborhood
Lorenzo Cesario, Tim Lichtenberg, Eleonora Alei +62
The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization to distances from th…
Evolution of stars with 60 and 200 Msun: predictions for WNh stars in the Milky Way
Alex Camilo Gormaz-Matamala, Amedeo Romagnolo, Krzysztof Belczynski
We study in detail the evolution of two massive stars at solar metallicity (), by calculating their final masses, radial expansion, and chemical enrichment. We run evoluti…
On the maximum black hole mass at solar metallicity
Amedeo Romagnolo, Alex C. Gormaz-Matamala, Krzysztof Belczynski
In high metallicity environments the mass that black holes (BHs) can reach just after core-collapse widely depends on how much mass their progenitor stars lose via winds. On one ha…
The role of stellar expansion on the formation of gravitational wave sources
A. Romagnolo, K. Belczynski, J. Klencki +3
Massive stars are the progenitors of black holes and neutron stars, the mergers of which can be detected with gravitational waves (GW). The expansion of massive stars is one of the…
The Uncertain Future of Massive Binaries Obscures the Origin of LIGO/Virgo Sources
K. Belczynski, A. Romagnolo, A. Olejak +6
The LIGO/Virgo gravitational--wave observatories have detected 50 BH-BH coalescences. This sample is large enough to have allowed several recent studies to draw conclusions about t…
Testing the presence of a dormant black hole inside HR 6819
A. Romagnolo, A. Olejak, A. Hypki +2
HR 6819 was recently reported to be a triple system with a dormant black hole (BH). The inner binary system was defined as a star estimated to be at the end of its main sequence an…
Large Interferometer For Exoplanets (LIFE): I. Improved exoplanet detection yield estimates for a large mid-infrared space-interferometer mission
S. P. Quanz, M. Ottiger, E. Fontanet +68
One of the long-term goals of exoplanet science is the atmospheric characterization of dozens of small exoplanets in order to understand their diversity and search for habitable wo…
A near-infrared interferometric survey of debris-disc stars. IV. An unbiased sample of 92 southern stars observed in H-band with VLTI/PIONIER
Steve Ertel, Olivier Absil, Denis Defrere +8
Context. Detecting and characterizing circumstellar dust is a way to study the architecture and evolution of planetary systems. Cold dust in debris disks only traces the outer regi…
