Beta Decay in Stellar Interiors

Physical Review, 1962
A study is made of the temperature and density dependence of beta-decay rates as they are affected by electron capture from continuum orbits, the absence of atomic binding energies, screening, and the exclusion principle. The rate of allowed electron capture from continuum orbits in a Fermi gas is calculated using the $V\ensuremath{-}A$ law; Coulomb ...

Adiabatic Processes in the Stellar Interior

2016
In this chapter we present a brief review of some reversible thermodynamic processes, in particular the adiabatic expansion or contraction as applied to the internal stellar layers.

Physical Conditions in the Stellar Interior

2016
This chapter establishes the main equations of the stellar structure, namely, the continuity equation and the hydrostatic equilibrium equation, and gives some estimates of the average density, pressure, and temperature. Finally, a discussion is made of the thermodynamic equilibrium and the stellar energy.

Nuclear Burning in Stellar Interiors

1992
The nuclear reactions in the stellar interior do not only produce the energy to make the star shine but also transform elements into others, like chemical reactions transform molecules into other molecules. As an example, we can consider the reaction $$ {}^{12}{\rm{C}} + {}^{{\rm{16}}}{\rm{O}} \to {}^{24}{\rm{Mg}} + {}^4{\rm{He}} $$ One 12C ...
