What variable determines wether a protostar becomes a star?
mass
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.
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.
If a protostar doesn't undergo a nuclear fusion what will it turn into?
If a protostar does not undergo nuclear fusion, it will not become a star. Instead, it will either become a brown dwarf, which is a failed star that lacks the mass to sustain nuclear fusion, or it will simply cool down into a cold, dense object known as a sub-stellar object.
How many degrees is a protostar?
A protostar does not have a fixed temperature in degrees like a fully formed star. It is in the process of forming and can have a range of temperatures depending on its size, mass, and stage of development.
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

These stars typically have lower luminosity and longer formation times compared to high-mass protostars.
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.
A contracting cloud of gas and dust with enough mass to form a star?
a protostar
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.
When a protostar of about one solar mass contracts and becomes hotter what position will it shift into?
Main sequence.
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.
