It depends on the size of the star forming. For a one solar-mass star it lasts about 1,000,000 years.
No, a protostar is basically the BEGINNING of a star's life cycle.
The stage that comes after the nebula in the star's life cycle is the protostar stage. During this stage, gravity causes the gas and dust within the nebula to clump together and heat up, eventually forming a dense, hot core. This marks the beginning of nuclear fusion within the protostar.
The third stage in the life cycle of a star is the main sequence stage, where a star fuses hydrogen into helium in its core. During this stage, stars like our Sun are stable and shine steadily due to the balance between gravitational forces pulling inward and nuclear fusion pushing outward. This stage can last for billions of years, depending on the mass of the star.
No, the sun is not a protostar. It is a mature star that is in the main sequence phase of its life cycle, where it fuses hydrogen into helium in its core. A protostar is a young star that is still in the process of accumulating mass and contracting before it begins hydrogen fusion in its core.
After a nebula, the next stage in the life cycle of a star is usually a protostar, where gravity causes the gas and dust within the nebula to begin collapsing and forming a dense core. Following this stage, the protostar may evolve into a main sequence star, where nuclear fusion begins in its core and it enters a stable period of energy production.
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
A Protostar.

the last stage of a beetle is an adult
The stage that comes first in the life cycle of a high-mass star is the main sequence stage. During this stage, the star fuses hydrogen into helium in its core, maintaining a balance between radiation pressure and gravity.
