The influence of metallicity on a combined stellar and disk evolution [PDF]
A&A 669, A84 (2023), 2022 The effects of an accretion disk are crucial to understanding the evolution of young stars. During the combined evolution, stellar and disk parameters influence each other, motivating a combined stellar and disk model. This makes a combined numerical model, evolving the disk alongside the star, the next logical step in the progress of studying early ...

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.

Photoevaporative Dispersal of Protoplanetary Disks around Evolving Intermediate-mass Stars [PDF]
ApJ (2021), 909, 109, 2021 We aim to understand the effect of stellar evolution on the evolution of protoplanetary disks. We focus in particular on the disk evolution around intermediate-mass (IM) stars, which evolve more rapidly than low-mass ones. We numerically solve the long-term evolution of disks around 0.5-5 solar-mass stars considering viscous accretion and ...

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

The evolution of stellar triples [PDF]
, 2020 Many stars do not live alone, but instead have one or more stellar companions. Observations show that these binaries, triples and higher-order multiples are common.

Classically and Asteroseismically Constrained 1D Stellar Evolution Models of α Centauri A and B Using Empirical Mixing Length Calibrations [PDF]
Astrophysical Journal, 2018 The bright, nearby binary α Centauri provides an excellent laboratory for testing stellar evolution models, because it is one of the few stellar systems for which we have high-precision classical (mass, radius, luminosity) and asteroseismic (p-mode ...

Mining gravitational-wave catalogs to understand binary stellar evolution: A new hierarchical Bayesian framework [PDF]
Physical Review D, 2018 Catalogs of stellar-mass compact binary systems detected by ground-based gravitational-wave instruments (such as LIGO and Virgo) will offer insights into the demographics of progenitor systems and the physics guiding stellar evolution.

Binary Black Hole Mergers from Field Triples: Properties, Rates, and the Impact of Stellar Evolution [PDF]
, 2017 We consider the formation of binary black hole (BH) mergers through the evolution of field massive triple stars. In this scenario, favorable conditions for the inspiral of a BH binary are initiated by its gravitational interaction with a distant ...
