Physics of stars and measurement data

TL;DR

This paper discusses the development of star physics based on astronomical measurement data, presenting theories that align well with observed data and advancing understanding of stellar properties and behaviors.

Contribution

It introduces a data-driven theoretical framework for star physics, including models of star interiors, binary star rotation, and solar oscillations, validated by measurement data.

Findings

The theory of hot star interiors matches observational data.

Distribution of stars over mass, radius, temperature, and luminosity is explained.

Predictions on binary star rotation and solar oscillations agree with measurements.

Abstract

Astrophysics = the star physics was beginning its development without a supporting of measurement data, which could not be obtained then. Still astrophysics exists without this support, although now astronomers collected a lot of valuable information. This is the main difference of astrophysics from all other branches of physics, for which foundations are measurement data. The creation of the theory of stars, which is based on the astronomical measurements data, is one of the main goals of modern astrophysics. Below the principal elements of star physics based on data of astronomical measurements are described. The theoretical description of a hot star interior is obtained. It explains the distribution of stars over their masses, mass-radius-temperature and mass-luminosity dependencies. The theory of the apsidal rotation of binary stars and the spectrum of solar oscillation is considered. All theoretical predictions are in a good agreement with the known measurement data, which confirms the validity of this consideration.
