Formation Channels of Gravitationally Resolvable Double White Dwarf Binaries Inside Globular Clusters
Lucas Hellström, Mirosław Giersz, Abbas Askar +6
Current gravitational wave detectors are sensitive to coalescing black holes and neutron stars. However, double white dwarfs (DWDs) have long been recognized as promising sources o…
Double white dwarf binary population in MOCCA star clusters -- Comparisons with observations of close and wide binaries
Lucas Hellström, Mirosław Giersz, Arkadiusz Hypki +3
There could be a significant population of double white dwarf binaries (DWDs) inside globular clusters (GCs), however, these are often too faint to be individually observed. We hav…
Influence of tidal dissipation on outcomes of binary-single encounters between stars and black holes in stellar clusters
Lucas Hellström, Abbas Askar, Alessandro A. Trani +3
In the cores of dense stellar clusters, close gravitational encounters between binary and single stars can frequently occur. Using the Tsunami code, we computed the outcome of a la…
A stellar census in globular clusters with MUSE: Binaries in NGC 3201
Benjamin Giesers, Sebastian Kamann, Stefan Dreizler +8
We utilize multi-epoch MUSE spectroscopy to study binaries in the core of NGC 3201. Our sample consists of 3553 stars with 54883 spectra in total comprising 3200 main-sequence star…
The DRAGON simulations: globular cluster evolution with a million stars
Long Wang, Rainer Spurzem, Sverre Aarseth +6
Introducing the DRAGON simulation project, we present direct -body simulations of four massive globular clusters (GCs) with stars and 5 primordial binaries at a high…
