What is Protostar ?

Protostar or Protostar is the primary stage of star formation. This formation, which takes thousands and thousands of years to finish, happens when the molecule contracts because of gasoline and magnetic stress.

A protostar is a younger star within the early phases of formation, earlier than reaching the primary sequence stage.

This stage of star formation can take 100,000 years or extra, relying on the dimensions of the star.

The fashionable depiction of protostars was first proposed by Chushiro Hayashi in 1966. The scale of protostars was drastically exaggerated in early fashions.

Later numerical calculations clarified the matter and confirmed that protostars are solely barely bigger than main-sequence stars of the identical mass.


When a protostar’s temperature is greater than 10 million Kelvin, it turns into a real star. At this temperature, hydrogen fusion begins to happen. Fusion heats the star, shrinking it into the core, inflicting the star to emit gentle. A protostar will need to have 0.08 photo voltaic lots to turn out to be a star.

A protostar begins as a gasoline cloud. Because the excessive gravity causes the cloud to break down, it begins to spin and creates a magnetic area. At this level, the protostar is usually obscured by gasoline clouds.

When the magnetic area creates the stellar wind, it elongates the gasoline and particles, revealing the forming star.
