Grigori Kuzmin and Stellar Dynamics
Open Astronomy, 2011 Grigori Kuzmin was a very gifted dynamicist and one of the towering figures in the distinguished history of the Tartu Observatory. He obtained a number of important results in relative isolation which were later rediscovered in the West.

Chandrasekhar and modern stellar dynamics [PDF]
, 2011 Stellar dynamics occupied Chandrasekhar's interest for a brief interlude between his more prolonged studies of stellar structure and radiative transfer. This paper traces the history of one of his ideas -- namely, that the shape of the galactic potential controls the orientation of the stellar velocity dispersion tensor.

On the Orbital Periods for a Particular Case of Spherical Symmetry [PDF]
Serbian Astronomical Journal, 2008 A particular case of steady state and spherical symmetry - the so-called logarithmic potential introduced as the first approximation for dark coronae of galaxies - is studied. Both time and angle dependence of the distance to the centre for the orbit of

Compact Binary Coalescences: Astrophysical Processes and Lessons Learned
Galaxies, 2022 On 11 February 2016, the LIGO and Virgo scientific collaborations announced the first direct detection of gravitational waves, a signal caught by the LIGO interferometers on 14 September 2015, and produced by the coalescence of two stellar-mass black ...

Lattice stellar dynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 1995 We describe a technique for solving the combined collisionless Boltzmann and Poisson equations in a discretised, or lattice, phase space. The time and the positions and velocities of `particles' take on integer values, and the forces are rounded to the nearest integer. The equations of motion are symplectic. In the limit of high resolution, the lattice

Estimating the Parameters of Extended Gravity Theories with the Schwarzschild Precession of S2 Star
Universe, 2021 After giving a short overview of previous results on constraining of Extended Gravity by stellar orbits, we discuss the Schwarzschild orbital precession of S2 star assuming the congruence with predictions of General Relativity (GR). At the moment, the S2

Universe, 2022 We estimate the parameters of the Hybrid Palatini gravity model with the Schwarzschild precession of S-stars, specifically of the S2, S38 and S55 stars. We also take into account the case of bulk mass distribution near the Galactic Center. We assume that
