Dynamical coupling of Keplerian orbits in a hierarchical four-body system: from the Galactic Centre to compact planetary systems
Myank Singhal, Ladislav Šubr, Jaroslav Haas
This study focuses on the long-term evolution of two bodies in nearby initially coplanar orbits around a central dominant body perturbed by a fourth body on a distant Keplerian orb…
Asymmetrical tidal tails of open star clusters: stars crossing their cluster's prah challenge Newtonian gravitation
Pavel Kroupa, Tereza Jerabkova, Ingo Thies +14
After their birth a significant fraction of all stars pass through the tidal threshold (prah) of their cluster of origin into the classical tidal tails. The asymmetry between the n…
The giants that were born swiftly -- Implications of the top-heavy stellar initial mass function on the birth conditions of globular clusters
Henriette Wirth, Pavel Kroupa, Jaroslav Haas +3
Recent results suggest that the initial mass function (IMF) of globular clusters (GCs) is metallicity and density dependent. Here it is studied how this variation affects the initi…
How many explosions does one need? -- Quantifying supernovae in globular clusters from iron abundance spreads
Henriette Wirth, Tereza Jerabkova, Zhiqiang Yan +3
Many globular clusters (GCs) are known to host multiple populations distinguishable by their light-element content. Less common are GCs displaying iron abundance spreads which are…
The properties of hypervelocity stars and S-stars originating from an eccentric disc around a supermassive black hole
Ladislav Subr, Jaroslav Haas
Hypervelocity stars (HVSs) that are observed in the Galactic halo, are believed to be accelerated to large velocities by a process of tidal disruption of binary stars passing close…
Rich Kozai-Lidov Dynamics in an Initially Thin and Eccentric Stellar Disc Around a Supermassive Black Hole
Jaroslav Haas, Ladislav Subr
There is growing evidence of star formation in the vicinity of supermassive black holes (SMBH) in galactic nuclei. A viable scenario for this process assumes infall of a massive ga…
Two-body relaxation driven evolution of the young stellar disc in the Galactic Centre
Ladislav Subr, Jaroslav Haas
The centre of our Galaxy hosts almost two hundreds of very young stars, a subset of which is orbiting the central supermassive black hole (SMBH) in a relatively thin disc-like stru…
Secular theory of the orbital evolution of the young stellar disc in the Galactic Centre
Jaroslav Haas, Ladislav Subr, David Vokrouhlicky
We investigate the orbital evolution of a system of N mutually interacting stars on initially circular orbits around the dominating central mass. We include perturbative influence…
The coupling of a young stellar disc with the molecular torus in the Galactic centre
Jaroslav Haas, Ladislav Subr, Pavel Kroupa
The Galactic centre hosts, according to observations, a number of early-type stars. About one half of those which are orbiting the central supermassive black hole on orbits with pr…
