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

Orbits, masses and dynamical parallaxes of 12 visual binary systems [PDF]
Serbian Astronomical Journal, 2003 In this paper the preliminary orbital elements are presented for the following double stars: WDS 00153+4412 = A 1256 AB, WDS 00470+2315 = HU 413, WDS 00520+3154 = A 924, WDS 01036+6341 = MLR 87, WDS 01131+2942 = A 1260, WDS 01158+0947 = A 2102, WDS 01200-

Chaotic Dynamics of Stellar Spin in Binaries and the Production of Misaligned Hot Jupiters
EPJ Web of Conferences, 2015 Motivated by observed hot Jupiter systems with high stellar obliquities, we examine the dynamics of stellar spin in planetary systems with distant stellar companions, with inclinations sufficiently high so that the planet undergoes Kozai-Lidov ...

Wrinkles in Time. I. Rapid Rotators Found in High-eccentricity Orbits
The Astrophysical Journal, 2023 Recent space-based missions have ushered in a new era of observational astronomy, where high-cadence photometric light curves for thousands to millions of stars in the solar neighborhood can be used to test and apply stellar age-dating methods, including

On Cluster Rotation in the Galactic Tidal Field
Open Astronomy, 2014 The dynamics of a rotating star cluster moving along a circular orbit in the axisymmetrical steady Galaxy is considered. The generalized tensor virial theorem allows to estimate its rotation speed.

A Physicist’s View of Stellar Dynamics: Dynamical Instability of Stellar Systems [PDF]
Highlights of Astronomy, 2005 AbstractI argue that the widely adopted framework of stellar dynamics survived since 1940s, is not fitting the current knowledge on non-linear systems. Borrowed from plasma physics when several fundamental features of perturbed non-linear systems were unknown, that framework ignores the difference in the role of perturbations in two different classes ...
