International audience; We explore with collisional gravitational N-body models the evolution of binary stars in initially fragmented and globally subvirial clusters of stars. Binaries are inserted in the (initially) clumpy configurations so as to ma

Resonant Disruption of Binary Stars by a Catalytic Black Hole

Autor: C. M. Boily

Publikováno v: Gravity and the Quantum ISBN: 9783319516998

The motion of a black hole (BH) about the centre of gravity of its host galaxy induces a strong response from the surrounding stars. We revisit the case of a harmonic potential and argue that half of the stars on circular orbits in that potential shi

This paper discusses a new method to generate self-coherent initial conditions for young substructured stellar cluster. The expansion of a uniform system allows stellar sub-structures (clumps) to grow from fragmentation modes by adiabatic cooling. We

Low-velocity streams in the solar neighbourhood caused by the Galactic bar

Autor: Olivier Bienaymé, I. Minchev, C. M. Boily, A. Siebert

Publikováno v: Monthly Notices of the Royal Astronomical Society. 407:2122-2130

We find that a steady state bar induces transient features at low velocities in the solar neighborhood velocity distribution due to the initial response of the disc, following the formation of the bar. We associate these velocity streams with two qua

Particle-based sampling ofN-body simulations

Publikováno v: Monthly Notices of the Royal Astronomical Society. 401:1898-1903

This paper introduces a novel approach for sampling the orbits of an N-body simulation. The gist of the method is to exploit individual phase-space coordinates acquired during integration of the equations of motion. This technique, which we dub ‘pa
