A Protostar doesn't really die. It is the early stage of star formation. If there is not enough mass you end up with a brown dwarf. If the mass is sufficient the next step is called a T Tauri star. The next phase would be a main-sequence star. Then depending on it's mass It will become a white dwarf or a red giant. If the red giant is massive enough the core collapse even more until the outer layers explode off, called a supernova. If the star was massive enough the core that is left behind will collapse into a neutron star or a black hole.
The force that turns a nebula into a protostar is gravity. As regions within a nebula become denser due to slight fluctuations in density, gravity pulls the surrounding gas and dust inward, causing the material to clump together. This process leads to the formation of a protostar as the collapsing material heats up and begins to accumulate mass. Once the temperature and pressure in the core become sufficient to initiate nuclear fusion, the protostar evolves into a main-sequence star.
The boxwood tree turns dark green after it dies. It is the only species of tree that turns that color after its life has ended.
A Protostar.
Turns yellow and dies
it turns brown and dies
A protostar is a young star in the early stages of formation, where nuclear fusion has not yet begun. A white dwarf is a small, dense star that is the remnant core of a low to medium mass star after it has exhausted its nuclear fuel.
yes
A protostar takes about 100,000 years to reach the main sequence.
A protostar is more like a stage previous to a star - before it ignites.
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
No. The sun was a protostar about 4.6 billion years ago.
A star life cycle takes millions of years. Some stars even last for billions of years, which can be older than our universe.
