Modeling of magneto-rotational stellar evolution [PDF]
Astronomy & Astrophysics, 2020 While magnetic fields have long been considered significant for the evolution of magnetic non-degenerate stars and compact stars, it has become clear in recent years that, in fact, all stars are deeply affected by their effects. This is particularly true

Convective H–He interactions in massive population III stellar evolution models [PDF]
, 2020 In Pop III stellar models convection-induced mixing between H- and He-rich burning layers can induce a burst of nuclear energy and thereby substantially alter the subsequent evolution and nucleosynthesis in the first massive stars.

Multiple Stellar Evolution: a population synthesis algorithm to model the stellar, binary, and dynamical evolution of multiple-star systems [PDF]
, 2020 In recent years, observations have shown that multiple-star systems such as hierarchical triple and quadruple-star systems are common, especially among massive stars.

parsec: stellar tracks and isochrones with the PAdova and TRieste Stellar Evolution Code [PDF]
, 2012 We present the updated version of the code used to compute stellar evolutionary tracks in Padova. It is the result of a thorough revision of the major in put physics, together with the inclusion of the pre‐main sequence phase, not present in our previous

Disentangling Stellar Age Estimates from Galactic Chemodynamical Evolution
The Astrophysical Journal, 2023 Stellar ages are key for determining the formation history of the Milky Way, but are difficult to measure precisely. Furthermore, methods that use chemical abundances to infer ages may entangle the intrinsic evolution of stars with the chemodynamical ...

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.
