Pulsating ULXs: large pulsed fraction excludes strong beaming
Alexander A. Mushtukov, Simon Portegies Zwart, Sergey S. Tsygankov +2
The recent discovery of pulsating ultra-luminous X-ray sources (ULXs) shows that the apparent luminosity of accreting neutron stars (NSs) can exceed the Eddington luminosity by a f…
Implementing Primordial Binaries in Simulations of Star Cluster Formation with a Hybrid MHD and Direct N-Body Method
Claude Cournoyer-Cloutier, Aaron Tran, Sean Lewis +6
The fraction of stars in binary systems within star clusters is important for their evolution, but what proportion of binaries form by dynamical processes after initial stellar acc…
Trimodal structure of Hercules stream explained by originating from bar resonances
Tetsuro Asano, Michiko S. Fujii, Junichi Baba +3
Gaia Data Release 2 revealed detailed structures of nearby stars in phase space. These include the Hercules stream, whose origin is still debated. Most of the previous numerical st…
Gargantuan chaotic gravitational three-body systems and their irreversibility to the Planck length
Tjarda Boekholt, Simon Portegies Zwart, Mauri Valtonen
Chaos is present in most stellar dynamical systems and manifests itself through the exponential growth of small perturbations. Exponential divergence drives time irreversibility an…
