Does IRS13 require an intermediate-mass black hole?
Václav Pavlík, Vladimír Karas, Florian Peißker +2
We investigate whether the Galactic-centre association IRS13 requires an intermediate-mass black hole (IMBH) to remain bound. Using high-precision -body calculations of IRS13-li…
Declarative bespoke modelling: A new approach
DBM Collaboration, David Komanek, Vaclav PavlÃk +2
Modern numerical models are increasingly complex, opaque, and computationally expensive, yet frequently fail to predict even qualitative features of observed phenomena. We propose…
When self-similarity meets mass spectrum and anisotropy
Václav PavlÃk
Self-similar evolution is widely used in the theory of collisional stellar dynamics, but its applicability to systems with multiple stellar masses is not well established. We inves…
Spatial mixing of stellar populations in globular clusters via binary-single star scattering
Václav PavlÃk, Melvyn B. Davies, Ellen I. Leitinger +5
The majority of Galactic globular star clusters (GCs) have been reported to contain at least two populations of stars (we use P1 for the primordial and P2 for the chemically-enrich…
Insights into spatial mixing of multiple populations in dynamically-young globular clusters
Václav PavlÃk, Melvyn B. Davies, Ellen I. Leitinger +5
Many galactic globular clusters (GCs) contain at least two stellar populations. Recent observational studies found that the radial distributions of the first (P1) and second popula…
Dynamics of star associations in an SMBH-IMBH system: The case of IRS13 in the Galactic centre
Václav PavlÃk, VladimÃr Karas, Bhavana Bhat +2
Context: The existence of intermediate-mass black holes (IMBHs) still poses challenges to theoretical and observational astronomers. Several candidates have been proposed, includin…
