Journal ArticleDOI
The gravitational wave signal from the Galactic disk population of binaries containing two compact objects.
TL;DR: In this paper, the properties of binary systems containing two compact objects, as derived by means of population synthesis, are discussed. But the authors focus on the binary systems that have a total mass above the Chandrasekhar limit and do not have a measurable frequency change.
Journal ArticleDOI
Population synthesis for double white dwarfs. I. Close detached systems.
TL;DR: In this article, the population of double white dwarfs in the Galaxy was modeled and a better agreement with observations compared to earlier studies was found, due to two modifications, the first is the treatment of the first phase of unstable mass transfer and the second the modelling of the cooling of the White dwarfs.
Journal ArticleDOI
Dynamical Formation of Close Binary Systems in Globular Clusters
David Pooley,Walter H. G. Lewin,Scott F. Anderson,Holger Baumgardt,Alexei V. Filippenko,Bryan Gaensler,Lee Homer,Piet Hut,V. M. Kaspi,V. M. Kaspi,Bruce Margon,Stephen L. W. McMillan,S.F. Portegies Zwart,M. van der Klis,F. Verbunt +14 more
TL;DR: In this paper, the authors present conclusive observational evidence for a link between the number of close binaries observed in X-rays in a globular cluster and the stellar encounter rate of the cluster.
Journal ArticleDOI
Stellar collisions during binary–binary and binary–single star interactions
TL;DR: In this paper, the authors study stellar collisions that occur during binary-single and binary-binary interactions, by performing numerical scattering experiments, and find that the normalized cross-section for at least one collision to occur (between any two of the four stars involved) is essentially unity.
Journal ArticleDOI
An analytical description of the disruption of star clusters in tidal fields with an application to Galactic open clusters
Henny J. G. L. M. Lamers,Mark Gieles,Nate Bastian,Holger Baumgardt,Nina V. Kharchenko,S.F. Portegies Zwart +5 more
TL;DR: In this article, a simple analytical description of the disruption of star clusters in a tidal field is presented, which can be used to predict the mass and age histograms of surviving clusters for any cluster initial mass function and any cluster formation history.
