What else can I help you with?
What variable determines wether a protostar becomes a star?
mass
What will a high mass protostar turn into?
A high mass protostar will eventually evolve into a massive star like a red supergiant, followed by a supernova explosion. After the supernova event, the remnants may form a neutron star or a black hole.
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.
Do prostars become stars?
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
why is a protostar the second phase of a star's life?
A protostar is the second phase of a star's life because it forms after a molecular cloud collapses under its own gravity, leading to the accumulation of material in a dense core. This core heats up as it contracts, eventually reaching temperatures and pressures sufficient to initiate nuclear fusion. The protostar stage is characterized by the gathering of mass and the development of a surrounding disk of gas and dust, which can eventually form planets. Once nuclear fusion begins in the core, the protostar evolves into a main sequence star.
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:)
What variable determines wether a protostar becomes a star?
mass
What is a contracting cloud of gas and dust with enough mass to form a star?
it's a protostar
What will a high mass protostar turn into?
A high mass protostar will eventually evolve into a massive star like a red supergiant, followed by a supernova explosion. After the supernova event, the remnants may form a neutron star or a black hole.
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
What is the difference between the protostar and the white dwarf?
A protostar is a young star in the early stages of formation, where nuclear fusion has not yet begun. A white dwarf is a small, dense star that is the remnant core of a low to medium mass star after it has exhausted its nuclear fuel.
What is a new star called?
A newly formed star is called a protostar. This is the early stage of a star's life cycle when it is still accumulating mass from its surrounding gas and dust. Once a protostar reaches a critical mass and temperature, nuclear fusion begins and it becomes a fully-fledged star.
What is the difference between a brown dwarf and a protostar?
A protostar is a star the is developing as is on the way to starting nuclear fusion. A brown dwarf is a failed star, one that failed to gather enough mass to start fusion.
Are protostar a star?
A protostar is more like a stage previous to a star - before it ignites.
How long does the protostar star life cycle stage last?
It depends on the size of the star forming. For a one solar-mass star it lasts about 1,000,000 years.
Why is the time from protostar to black hole shorter than the time from protostar to white dwarf?
The mass of the progenitor star has to be massive to form a black hole and thus it will have a shorter time on the main sequence compared to a medium sized star.
