Hi,
Does anybody know a place where i can find a list of electron densities of stars?

Electron density is a measure of the number of electrons per unit volume in a given material. In stars, it is related to the number of electrons present in the plasma, which is the hot, ionized gas that makes up the majority of a star's interior.
Electron density in stars is typically measured using spectroscopic techniques. By analyzing the absorption or emission lines of certain elements, scientists can determine the density of the plasma in the star's atmosphere. Other methods, such as radio interferometry, can also be used to measure electron density.
The electron density of a star is influenced by several factors, including its temperature, pressure, and composition. Generally, higher temperatures and pressures result in higher electron densities, while elements with more electrons, such as metals, also contribute to higher densities.
The electron density of a star plays a crucial role in determining its structure and evolution. It affects the star's opacity, or its ability to absorb and emit radiation, which in turn impacts its energy production and temperature. Higher electron densities can also lead to more intense magnetic fields and stronger winds, which can influence a star's behavior and its interaction with its surroundings.
The electron density of stars can vary significantly depending on the type of star. For example, white dwarfs, which are very dense and compact stars, have much higher electron densities than larger, less dense stars like red giants. The electron density can also change over the course of a star's lifetime, as it evolves and goes through different stages of fusion and nuclear reactions.
