Binary black hole mergers from field triples: properties, rates and the impact of stellar evolution
Fabio Antonini, Silvia Toonen, Adrian S. Hamers
We consider the formation of binary black hole mergers through the evolution of field massive triple stars. In this scenario, favorable conditions for the inspiral of a black hole…
Relaxation near supermassive black holes driven by nuclear spiral arms: anisotropic hypervelocity stars, S-stars and tidal disruption events
Adrian S. Hamers, Hagai B. Perets
Nuclear spiral arms are small-scale transient spiral structures found in the centers of galaxies. Similarly to their galactic-scale counterparts, nuclear spiral arms can perturb th…
Probing the formation of planetesimals in the Galactic Centre using Sgr A* flares
Adrian S. Hamers, Simon F. Portegies Zwart
Flares in X-ray and near infrared are observed above the quiescent emission of the supermassive black hole (SBH) in the Galactic Centre (GC) at a rate of approximately once per day…
Relativistic dynamics of stars near a supermassive black hole
Adrian S. Hamers, Simon F. Portegies Zwart, David Merritt
General relativistic precession limits the ability of gravitational encounters to increase the eccentricity of orbits near a supermassive black hole (SBH). This "Schwarzschild…
