Which part of the hertzsprung Russell diagram is occupied by protostars?

Protostars are found in the lower right portion of the Hertzsprung-Russell diagram, specifically in the region known as the T Tauri phase. This is where stars are still in the early stages of formation and have not yet begun sustained nuclear fusion in their cores.


Where are stars on the hr diagram?

The HR diagram contains only stars - so everywhere.

Why is the hr diagram important to scientist?

The Hertzsprung-Russell diagram helps scientists understand the life cycle of stars by showing the relationship between a star's luminosity and temperature. It enables astronomers to classify stars based on their evolutionary stage and predict their future evolution. This diagram is essential for studying the properties and behavior of stars within galaxies.


Why are black dwarfs not on a HR diagram?

Black dwarfs are not on the Hertzsprung-Russell diagram because they are theoretical end points in stellar evolution where white dwarfs cool down to become invisible. Their low temperature and luminosity levels make them undetectable in the visible spectrum, so they do not appear on the HR diagram.
