The Impact of High-Mass Clusters on the Binary Black Hole Merger Rate over Cosmic Time
Aidan Mai, Kyle Kremer, Fulya Kıroğlu
We present a cosmological calculation of the binary black hole merger rate from dense star clusters, using a () model grid spanning the…
Discovery of over a thousand variable stars in Terzan 5 and Liller 1 with JWST
Kevin B. Burdge, Ilaria Caiazzo, Malina M. Desai +18
The Bulge Fossil Fragments Terzan 5 and Liller 1 host some of the densest stellar environments in the Galaxy, yet their variable star populations have remained largely unexplored d…
Using Machine Learning to Model Stellar Collisions in our Galactic Center
Tristan C. Sand, Sanaea C. Rose, Elena González Prieto +8
Direct collisions in the inner pc of the Galactic center can alter the orbits and properties of stars. The outcome of a collision depends on a number of parameters, including the m…
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.…
Formation of rotating supergiants via stellar mergers in dense clusters: Implications for black hole natal spins
Ishaan Satish, Kyle Kremer, Fulya Kıroğlu +2
We investigate how massive stellar mergers in young star clusters imprint on black hole spin distributions and the broader implications for gravitational wave sources. The central…
Formation of Black Hole-White Dwarf X-ray Binaries in Globular Clusters
William Y. W. Yang, Kyle Kremer, James C. Lombardi +1
Globular clusters are host to significant populations of dynamically-active stellar remnants that connect to a variety of astrophysical sources. Using simulations performed with th…
Red vs. Blue: How metallicity shapes black hole dynamics and mergers in dense star clusters
Saloni Agrawal, Kyle Kremer, Michael Zevin +6
Dense star clusters are a well-established environment for the formation of gravitational wave sources through dynamical interactions. Recent LIGO-Virgo-KAGRA (LVK) events such as…
Black hole mergers from dense star clusters with realistic binary populations
Christopher E. O'Connor, Kyle Kremer, Saloni Agrawal +5
We present a suite of 24 full-lifetime simulations of dense star clusters with the Cluster Monte Carlo (CMC) code, featuring updated input physics and a realistic distribution of i…
The diverse outcomes of binary white dwarf mergers and connections to Galactic LISA sources
Kyle Kremer, Katelyn Breivik, Claire S. Ye
In the coming decade, the millihertz gravitational wave observatory LISA will provide the best constraints yet on the tens of thousands of close white dwarf binaries in the Milky W…
An analytical approach to binary populations in globular clusters
Christopher E. O'Connor, Kyle Kremer, Frederic A. Rasio
Globular clusters (GCs) display much lower binary fractions than found among main-sequence stars in the solar neighborhood. The physical cause of this difference is debatable: does…
Discovery of a double white dwarf in the Galactic globular cluster NGC 6397
Fabian Göttgens, Marilyn Latour, Ulrich Heber +4
Binaries in the cores of globular clusters are known to prevent the gravitational collapse of the cluster, and simulations predict that the core of NGC 6397 contains a large number…
Machine Learning Methods for Stellar Collisions. I. Predicting Outcomes of SPH Simulations
Elena González Prieto, James C. Lombardi, Sanaea C. Rose +7
Stellar collisions can occur frequently in dense cluster environments, and play a crucial role in producing exotic phenomena from blue stragglers in globular clusters to high-energ…
