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 Pavlík +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 Pavlík
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…
Insights into spatial mixing of multiple populations in dynamically-young globular clusters
Václav Pavlík, 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…
Spatial mixing of stellar populations in globular clusters via binary-single star scattering
Václav Pavlík, 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…
Dynamics of star associations in an SMBH-IMBH system: The case of IRS13 in the Galactic centre
Václav Pavlík, Vladimír 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…
Dynamics of star clusters with tangentially anisotropic velocity distribution
Václav Pavlík, Douglas C. Heggie, Anna Lisa Varri +1
Recent high-precision observations with HST and Gaia enabled new investigations of the internal kinematics of star clusters (SCs) and the dependence of kinematic properties on the…
Fostering innovation, inclusion, and diversity in astronomy education: The Czech Astronomy Olympiad experience
Václav Pavlík, Jakub Vošmera, Tomáš Gráf +1
Astronomy education and outreach are very important when it comes to the future generation's interest in science. The Czech Astronomy Olympiad shows how an educational competition…
Environmental Effects on the Dynamical Evolution of Star Clusters in Turbulent Molecular Clouds
Paolo Suin, Steven N. Shore, Václav Pavlík
Context: Star clusters form within giant molecular clouds that are strongly altered by the feedback action of the massive stars, but the cluster still remains embedded in a dense,…
Mass segregation and dynamics of primordial binaries in star clusters with a radially anisotropic velocity distribution
Václav Pavlík, Enrico Vesperini
This paper is the third in a series investigating, by means of -body simulations, the implications of an initial radially anisotropic velocity distribution on the dynamics of st…
Evolution towards energy equipartition in star clusters: effects of the tidal field, primordial binaries, and internal velocity anisotropy
Václav Pavlík, Enrico Vesperini
This paper is the second in a series investigating the evolution of star clusters towards energy equipartition (EEP). Here, we focus on the effects of the external tidal field of t…
