No, a protostar is basically the BEGINNING of a star's life cycle.
what is the third stage of the star cycle
A star life cycle takes millions of years. Some stars even last for billions of years, which can be older than our universe.
protostar, main sequence, giant, nebula, white dwarf & black dwarf.
During the life cycle of massive stars, when carbon fuses to form neon and magnesium.
It depends on the size of the star forming. For a one solar-mass star it lasts about 1,000,000 years.
the answer is a protostar
A Protostar.
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
the answer is a protostar

what is the third stage of the star cycle
Protostar!
A star life cycle takes millions of years. Some stars even last for billions of years, which can be older than our universe.
It is called a protostar, as it is beginning to form the spherical shape and collecting hydrogen due to its growing mass and gravitational attraction.
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
The "protostar". That's not classed as a true star, but I think that's the answer.
