Chemical element transport in stellar evolution models [PDF]

open access: yesRoyal Society Open Science, 2017
Stellar evolution computations provide the foundation of several methods applied to study the evolutionary properties of stars and stellar populations, both Galactic and extragalactic.

Binarity and Stellar Evolution [PDF]

open access: yesProceedings of the International Astronomical Union, 2011
AbstractModels of stellar evolution constitute an extremely powerful, and for the most part apparently very successful, tool for understanding the progression of a star through its lifetime as a fairly compact entity of incandescent gas. That success has led to stellar evolution theory becoming a crutch when an observer is faced with objects whose ...

Intriguing Revelations from Lithium, Beryllium, and Boron

open access: yesThe Astrophysical Journal, 2023
This is a report on some highlights of research on the rare light elements, lithium (Li), beryllium (Be), and boron (B), that were presented at my Henry Norris Russell Lecture in 2020 January.

A new 12C+12C reaction rate: Impact on stellar evolution [PDF]

open access: yesEPJ Web of Conferences, 2023
Among the reactions driving stellar evolution during carbon burning, 12C + 12C fusion provides the key ingredients. This system reveals many resonances, but also regions with suppressed fusion cross-sections.

Fundamentals of stellar evolution and nucleosynthesis [PDF]

open access: yesEPJ Web of Conferences
The theory of stellar structure and evolution plays a pivotal role in modern astrophysics. Stellar evolution calculations are used to determine the ages and, to a lesser extent, distances of stars, which are critical to our knowledge of the history and ...

Stellar Chemical Evolution [PDF]

open access: yesSymposium - International Astronomical Union, 1997
One of the major achievements of astrophysics has been the demonstration that most of the chemical elements have been synthesized in stars: nucleosynthesis calculations of homogeneous and inhomogeneous big bang cosmologies show that, in comparison with the most metal-poor stars currently known, essentially no elements heavier than B existed at the era ...

The Power of Asteroseismology for Early Stellar Evolution

open access: yesFrontiers 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 ...
