Energy equipartition in Globular Clusters through the eyes of dynamical models
M. Teodori, O. Straniero, M. Merafina
Gravitational encounters drive globular clusters toward energy equipartition, mass segregation and evaporation altering structural, spatial and kinematic features. We determine the…
Orbital precession and other properties of two-body motion in the presence of dark energy
Gennady S. Bisnovatyi-Kogan, Marco Merafina
We consider the Kepler two-body problem in the presence of a cosmological constant Lambda. Several dimensionless parameters characterizing the possible orbit typologies are used to…
Generalization of the Fokker-Planck equation for stellar orbit diffusion in multi-mass star systems
Marco Merafina, Matteo Teodori
We improve the standard theory of collisional stellar systems by considering the presence of a continuous mass distribution. The calculus of the diffusion coefficients is generaliz…
On self-gravitating strange dark matter halos around galaxies
Marco Merafina, Francesco G. Saturni, Catalina Curceanu +2
A new family of nonrelativistic, Newtonian, non-quantum equilibrium configurations describing galactic halos is introduced, by considering strange quark matter conglomerates with m…
Two body problem in presence of cosmological constant
G. S. Bisnovatyi-Kogan, M. Merafina
We consider the Kepler two-body problem in presence of the cosmological constant . Contrary to the classical case, where finite solutions exist for any angular momentum of the s…
Massive black holes interactions during the assembly of heavy sub-structures in the centre of galaxy clusters
M. Donnari, M. Arca-Sedda, M. Merafina
We performed a series of direct N-body simulations with the aim to follow the dynamical evolution of a galaxy cluster (GC) () in different environ…
