The Power of Asteroseismology for Early Stellar Evolution
Frontiers in Astronomy and Space Sciences, 2019 Stars are the building blocks of planetary systems, clusters, associations, and galaxies. The evolution of stars is driven by physical processes in their interiors making theory of stellar interior structure and evolution an important ingredient of ...

First results from the TNG50 simulation: the evolution of stellar and gaseous discs across cosmic time [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present a new cosmological, magnetohydrodynamical simulation for galaxy formation: TNG50, the third and final instalment of the IllustrisTNG project. TNG50 evolves 2 × 21603 dark matter particles and gas cells in a volume 50 comoving Mpc across.

A Review of the Mixing Length Theory of Convection in 1D Stellar Modeling
Galaxies, 2023 We review the application of the one-dimensional Mixing Length Theory (MLT) model of convection in stellar interiors and low-mass stellar evolution.

Rotation and Stellar Evolution [PDF]
Symposium - International Astronomical Union, 1981 Does rotation influence stellar evolution? Does it cause observational effects other than line broadening? Can rotation be responsible for mixing of chemical elements throughout the star? Do evolved stars have rapidly rotating cores? This, for instance, is of interest if one wants to compute the details of supernova events.

On the parallelization of stellar evolution codes [PDF]
Computational Astrophysics and Cosmology, 2018 AbstractMultidimensional nucleosynthesis studies with hundreds of nuclei linked through thousands of nuclear processes are still computationally prohibitive. To date, most nucleosynthesis studies rely either on hydrostatic/hydrodynamic simulations in spherical symmetry, or on post-processing simulations using temperature and density versus time ...

Dawes Review 6: The Impact of Companions on Stellar Evolution [PDF]
Publications Astronomical Society of Australia, 2016 Astrophysicists are increasingly taking into account the effects of orbiting companions on stellar evolution. New discoveries have underlined the role of binary star interactions in a range of astrophysical events, including some that were previously ...

Evolution of the Stellar Mass--Metallicity Relation - I: Galaxies in the z~0.4 Cluster Cl0024 [PDF]
, 2018 We present the stellar mass-stellar metallicity relationship (MZR) in the Cl0024+1654 galaxy cluster at z~0.4 using full spectrum stellar population synthesis modeling of individual quiescent galaxies. The lower limit of our stellar mass range is $M_*=10^

Planetary Engulfment Prognosis within the ρ CrB System
The Astrophysical Journal, 2023 Exoplanets have been detected around stars at various stages of their lives, ranging from young stars emerging from formation to the latter stages of evolution, including white dwarfs and neutron stars.
