Element diffusion in stellar interiors
Astrophysical Journal, 1990 Simple equations are derived that describe element diffusion in radiative stellar interiors and that may be incorporated in standard stellar evolution codes. For the sun, diffusion is expected to increase the predicted event rates in the Cl-37 solar neutrino experiment and in electron-neutrino scattering experiments by 5 - 10 percent; the expected ...

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.

Lithium in Turnoff Stars in the Globular Cluster M5: A Quest for Primordial Lithium
The Astrophysical Journal, 2023 The light element lithium is formed by nucleosynthesis during the Big Bang. Its abundance can help to define the parameters of the early Universe. To find this primordial value, it is necessary to determine Li abundances in the oldest stars because it is

The Astrophysical Journal, 2023 To decipher complex patterns of gravity-mode period spacings observed for intermediate-mass main-sequence stars is an important step toward a better understanding of the structure and dynamics in the deep radiative region of the stars.

Universe, 2021 The slow neutron-capture process (s-process) efficiency in low-mass AGB stars (1.5 < M/M⊙ < 3) critically depends on how mixing processes in stellar interiors are handled, which is still affected by considerable uncertainties.

Asteroseismic Investigation on KIC 10526294 to Probe Convective Core Overshoot Mixing
The Astrophysical Journal, 2023 In the overshoot mixing model with an exponentially decreasing diffusion coefficient, the initial value of the diffusion coefficient plays a crucial role.

Sounding stellar interiors [PDF]
Symposium - International Astronomical Union, 1997 Multimode pulsations have been discovered in a large variety of main sequence stars and white dwarfs. There are abundant and accurate data on p- and g- mode frequencies in these objects. So far, however, use of these data for sounding interiors has been very limited.

Magnetohydrodynamics of stellar interiors [PDF]
Astronomy and Geophysics, 2005 David Hughes, Robert Rosner and Nigel Weiss describe what was achieved during a programme on stellar magnetic fields at the Isaac Newton Institute in Cambridge. Over a four-month period more than 90 participants visited the Institute for a mixture of structured workshops and informal collaboration.
