Turbulent convection and pulsation stability of stars - I. Basic equations for calculations of stellar structure and oscillations [PDF]
, 2015 Starting from hydrodynamic equations, we have established a set of hydrodynamic equations for average flow and a set of dynamic equations of auto- and cross-correlations of turbulent velocity and temperature fluctuations, following the classic Reynold's ...

Stellar-mass black holes in young massive and open stellar clusters – IV. Updated stellar-evolutionary and black hole spin models and comparisons with the LIGO-Virgo O1/O2 merger-event data [PDF]
Monthly notices of the Royal Astronomical Society, 2020 I present a set of long-term, direct, relativistic many-body computations of model dense stellar clusters with up-to-date stellar-evolutionary, supernova (SN), and remnant natal-kick models, including pair instability and pulsation pair instability ...

RADIAL STELLAR PULSATION AND THREE-DIMENSIONAL CONVECTION. III. COMPARISON OF TWO-DIMENSIONAL AND THREE-DIMENSIONAL CONVECTION EFFECTS ON RADIAL PULSATION [PDF]
, 2014 We have developed a multi-dimensional radiation hydrodynamics code to simulate the interaction of radial stellar pulsation and convection for full-amplitude pulsating models. Convection is computed using large eddy simulations.

The Contour Method: a New Approach to Finding Modes of Nonadiabatic Stellar Pulsations [PDF]
Astrophysical Journal, 2020 The contour method is a new approach to calculating the nonadiabatic pulsation frequencies of stars. These frequencies can be found by solving for the complex roots of a characteristic equation constructed from the linear nonadiabatic stellar pulsation ...

Why should we correct reported pulsation frequencies for stellar line-of-sight Doppler velocity shifts? [PDF]
, 2014 In the age of Kepler and CoRoT, extended observations have provided estimates of stellar pulsation frequencies that have achieved new levels of precision, regularly exceeding fractional levels of a few parts in 10 4 .

Pulsating Stellar Atmospheres [PDF]
Symposium - International Astronomical Union, 1997 We review the basic concepts, present state of theoretical models, and the future prospects for theory and observations of pulsating stellar atmospheres. Our emphasis is on radially pulsating cool stars, which dynamic atmospheres provide a general example for the differences with standard static model atmospheres.

Interaction Between Convection and Pulsation
Living Reviews in Solar Physics, 2015 This article reviews our current understanding of modelling convection dynamics in stars. Several semi-analytical time-dependent convection models have been proposed for pulsating one-dimensional stellar structures with different formulations for how the
