A Review of the Mixing Length Theory of Convection in 1D Stellar Modeling

open access: yesGalaxies, 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 rate of the solar core as a key constraint to magnetic angular momentum transport in stellar interiors [PDF]

open access: yesAstronomy and Astrophysics, 2019
Context. The internal rotation of the Sun constitutes a fundamental constraint when modelling angular momentum transport in stellar interiors. In addition to the more external regions of the solar radiative zone probed by pressure modes, measurements of rotational splittings of gravity modes would offer an invaluable constraint on the rotation of the ...

Simulations of the Onset and Dynamical Evolution of Inertial Waves in Solar/Stellar Interior

open access: yesThe Astrophysical Journal
Inertial modes have been recently detected in the Sun via helioseismology, yet their origin, evolution, and role in the dynamics of the solar plasma and magnetic field remain poorly understood.

Magnetism, dynamo action and the solar-stellar connection

open access: yesLiving Reviews in Solar Physics, 2017
The Sun and other stars are magnetic: magnetism pervades their interiors and affects their evolution in a variety of ways. In the Sun, both the fields themselves and their influence on other phenomena can be uncovered in exquisite detail, but these ...

Solar-Like Oscillators in the Kepler Era: A Review

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Many late-type stars across the Milky Way exhibit observable pulsations similar to our Sun that open up a window into stellar interiors. The NASA Kepler mission, a space-based photometric telescope, measured the micro-magnitude luminosity fluctuations ...

News on the slow neutron capture process in AGB stars [PDF]

open access: yesEPJ Web of Conferences, 2023
Asymptotic giant branch (AGB) stars are responsible for the production of the main component of the solar s-process distribution. Despite enormous progress in the theoretical modeling of these objects over the last few decades, many uncertainties remain.

The Missing Link: Testing Galactic Chemical Evolution Models with the First Multi-isotopic Abundances in Solar Twin Stars

open access: yesThe Astrophysical Journal, 2023
We present the first isotopic abundances of both ^13 CO and C ^18 O in solar twin stars and test the results against several galactic chemical evolution (GCE) models with different nucleosynthesis prescriptions.

Ionization potential depression and ionization balance in dense carbon plasma under solar and stellar interior conditions [PDF]

open access: yesAstronomy & Astrophysics, 2020
Recent quantitative experiments on the ionization potential depression (IPD) in dense plasma show that the observational results are difficult to explain with the widely used analytical models for plasma screening. Here, we investigate the effect of plasma screening on the IPD and ionization balance of dense carbon plasma under solar and stellar ...
