In astrophysics, barotropic fluids are important in the study of stellar interiors or of the interstellar medium.

The study of stellar interiors using their pulsations is asteroseismology.

In stellar interiors the temperatures are very high.

He also contributed to accurate astrophysical models of stellar interiors.

The photosphere floats atop the deep hydrogen convection zones of the stellar interior.

You need to know some fluid dynamics to understand how stellar interiors work.

He developed his model despite knowingly lacking firm foundations for understanding opacity and energy generation in the stellar interior.

This means that their abundances depend strongly on how much mixing occurs in stellar interiors.

His final topic is the work during the 1950s he undertook on stellar interiors using the Institute for Advanced Study computer.

The radiation zone is the region within the stellar interior where radiative transfer is sufficiently efficient to maintain the flux of energy.
