A protostar is the first building block of the main star. As it has not yet accumulated enough mass to join the main sequence, it will be smaller than the main star.
The next stage will be a T Tauri star.
a high mass prostar turns into a high mass star
Protostar!

The core of the protostar reached an extremely high temperature
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
That depends on the mass of the proto-star.
a low mass protostar is the begining formation of a low mass star. a low mass protostar is formed by a nebula (stellar nursery), like a cloud in space, where all stares come from. the definition of protostar is: a collection of gas, and dust who`s gravitational pull is causing it to collapse on itself & form a star. a LOW MASS protostar just has a LOWER MASS then a HIGH MASS protostar. Your Welcome:)
Protostar!
Sometimes. If the total mass is high enough, and if the cloud of dust and gas collapse to reach a high enough density and pressure, nuclear fusion can begin in the core and it will become a star. If the total mass is not high enough, it may collapse into a "brown dwarf".
The life of a high mass star goes like this: A nebula gets hot and nuclear fusion binds it into a high-mass protostar the protostar ages into high-mass, very hot star that hot star explodes into a supergiant, which proceeds to explode into a supernova the supernova then shrinks into a neutron star or a black hole the life of a low- or medium-mass star goes like this: a nebula gets hot and nuclear fusion binds it into a low-mass protostar the protostar ages into a low- or medium- mass,cool star the star explodes into a red giant, the red giant explodes into a planetary nebula the nebula shrinks into a white dwarf, which then dims into a black dwarf i hope i was able to answer your question.
It must collect enough mass in order for gravity to be able to turn it into a sphere.
mass
The formation of a protostar from a nebula. As the protostar forms, it accretes more mass from the cloud and spins. As it gains more mass, it eventually becomes massive enough to ignite the core and become a star. The protostar is the first step in the evolution of any star.
