Stellar-mass black holes in young massive and open stellar clusters and their role in gravitational-wave generation III: dissecting black hole dynamics [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Stellar-remnant black holes (BH) in dense stellar clusters comprise a natural setup to trigger general-relativistic (GR) inspiral and merger of binary black holes (BBH), detectable by the LISA and the LIGO-Virgo, through dynamical encounters inside such ...

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).

A fast multipole method for stellar dynamics [PDF]
, 2014 The approximate computation of all gravitational forces between N interacting particles via the fast multipole method (FMM) can be made as accurate as direct summation, but requires less than O(N) operations.

Stellar dynamics in gas: the role of gas damping [PDF]
, 2014 In this paper, we consider how gas damping affects the dynamical evolution of gas-embedded star clusters. Using a simple three-component (i.e. one gas and two stellar components) model, we compare the rates of mass segregation due to two-body relaxation,

The Mechanism and Timescale of Nodal Precession: Two Nuclear Stellar Disks in the Galactic Center
Open Astronomy, 2015 A dynamical model of interacting nuclear stellar rings in the central parsec of our Galaxy is constructed. We discuss the physical sources of nodal precession and of the associated time scales.

Dark matter in massive early-type galaxies: 100 years of the jeans equations [PDF]
Serbian Astronomical Journal, 2019 In 1919 James Jeans published the book Problems of Cosmogony and Stellar Dynamics in which he summarized his work on dynamics of stellar systems based on his papers published from 1915 onwards.

Continuous stellar mass-loss in N-body models of galaxies [PDF]
, 2001 We present an N-body computer code - aimed at studies of galactic dynamics - with a CPU-efficient algorithm for a continuous (i.e. time-dependent) stellar mass-loss. First, we summarize available data on stellar mass-loss and derive the long-term (20 Gyr)

IN-SYNC. V. Stellar Kinematics and Dynamics in the Orion A Molecular Cloud [PDF]
, 2017 The kinematics and dynamics of young stellar populations enable us to test theories of star formation. With this aim, we continue our analysis of the SDSS-III/APOGEE IN-SYNC survey, a high-resolution near-infrared spectroscopic survey of young clusters ...

Open Astronomy, 2014 Distribution functions are found for some models of mass distribution in infinitely thin disks with an elliptical velocity distribution (Maclaurin, Kuzmin-Toomre, Hénon and Mestel disks).

Central dark matter trends in early-type galaxies from strong lensing, dynamics and stellar populations [PDF]
, 2010 We analyze the correlations between central dark matter (DM) content of early-type galaxies and their sizes and ages, using a sample of intermediate-redshift (z ~ 0.2) gravitational lenses from the SLACS survey, and by comparing them to a larger sample ...
