What is a low-mass protostar?
A low-mass protostar is a young star in the early stages of formation that has a relatively low mass compared to other stars. It is in the process of accumulating material from a surrounding gas and dust cloud and undergoing gravitational collapse to eventually ignite nuclear fusion in its core. These stars typically have lower luminosity and longer formation times compared to high-mass protostars.
What variable determines wether a protostar becomes a star?
mass
When fusion begins in a high mass protostar which kind of star is formed?
When fusion begins in a high-mass protostar, it typically forms a massive main-sequence star, often classified as an O-type or B-type star. These stars are characterized by their high temperatures, significant luminosity, and large mass, typically exceeding eight solar masses. They evolve rapidly due to their intense nuclear fusion processes and have relatively short lifespans, eventually leading to supernova events or the formation of black holes or neutron stars.
What does mass of the star do in protostar?
The mass of a protostar plays a crucial role in its evolution and eventual fate. A higher mass protostar will generate more heat and pressure, leading to a faster rate of nuclear fusion when it reaches the main sequence stage. Conversely, lower mass protostars will fuse hydrogen more slowly, resulting in a longer lifespan. Ultimately, the mass determines the star's temperature, luminosity, and the type of stellar remnant it will leave behind at the end of its life cycle.
Which stage comes first in the life cycle of a high-mass star?
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.
What is the definition of a low mass 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:)
How is a protostar created?
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".
What happens to a protostar to eventually form a main sequence star?
It must collect enough mass in order for gravity to be able to turn it into a sphere.
What is a contracting cloud of gas and dust with enough mass to form a star?
it's a protostar

What variable determines wether a protostar becomes a star?
mass
What is the first step of stellar evolution?
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.

Protostar will turn into what kind of star?
Protostars will eventually evolve into main sequence stars, where they will spend the majority of their lifetime fusing hydrogen into helium in their cores. The exact path of evolution will depend on factors such as mass, temperature, and composition.
What does each star explode into?
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.
