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

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

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 ...

Three-dimensional Simulations of Massive Stars. II. Age Dependence
The Astrophysical Journal, 2023 We present 3D full star simulations, reaching up to 90% of the total stellar radius, for three 7 M _⊙ stars of different ages: zero-age main sequence (ZAMS), mid–main sequence (midMS), and terminal-age main sequence (TAMS).

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.
