Formation and merging of Mass Gap Black Holes in Gravitational Wave Merger Events from Wide Hierarchical Quadruple Systems
Mohammadtaher Safarzadeh, Adrian S. Hamers, Abraham Loeb +1
We investigate secular evolution in hierarchical quadruple systems as a formation channel of mass-gap black holes (with masses of about ) in systems that will even…
Double neutron star mergers from hierarchical triple-star systems
Adrian S. Hamers, Todd A. Thompson
The isolated binary evolution model for merging neutron stars (NSs) involves processes such as mass transfer, common-envelope evolution, and natal kicks, all of which are poorly un…
Analytic computation of the secular effects of encounters on a binary: third-order perturbation, octupole, and post-Newtonian terms; steady-state distribution
Adrian S. Hamers, Johan Samsing
Dense stellar systems such as globular clusters are believed to harbor merging binary black holes (BHs). The evolution of such binaries is driven by interactions with other stars,…
The Effect of Distant Encounters on Black Hole Binaries in Globular Clusters: Systematic Increase of In-cluster Mergers in the LISA band
Johan Samsing, Adrian S. Hamers, Jacob G. Tyles
We present the first systematic study on how distant weak interactions impact the dynamical evolution of merging binary black holes (BBHs) in dense stellar clusters. Recent studies…
The impact of white dwarf natal kicks and stellar flybys on the rates of Type Ia supernovae in triple-star systems
Adrian S. Hamers, Todd A. Thompson
Type Ia supernovae (SNe Ia) could arise from mergers of carbon-oxygen white dwarfs (WDs) triggered by Lidov-Kozai (LK) oscillations in hierarchical triple-star systems. However, pr…
Analytic computation of the secular effects of encounters on a binary: features arising from second-order perturbation theory
Adrian S. Hamers, Johan Samsing
Binary-single interactions play a crucial role in the evolution of dense stellar systems such as globular clusters. In addition, they are believed to drive black hole (BH) binary m…
