A protostar is when a large gaseous cloud is coming together under gravity, in the early stages of a stars formation. The gaseous mass of the protostar has not got to the stage at which nuclear fusion reactions are taking place. The gas becomes hotter and more dense, until finally there is enough pressure and temperature to allow the hydrogen to fuse together, giving off energy as a main sequence star.
What else can I help you with?
Which is a star in its old age Protostar Main sequence Black Hole or Red giant?
A red giant is a star in its old age. During this stage, a star expands and cools as it exhausts its hydrogen fuel. Eventually, it will shed its outer layers, forming a planetary nebula.
What is the diffrance between a white dwarf and a red giant?
There are huge differences in:Size (diameter)DensityColorEnergy production (white dwarves no longer produce energy)Brightness
When a red giant completes helium fusion and collapses it becomes a . protostar red dwarf white dwarf neutron star black hole?
When a red giant completes helium fusion, it typically sheds its outer layers, resulting in a planetary nebula. The core that remains becomes a white dwarf, which is a dense, hot remnant composed mostly of carbon and oxygen. Over time, the white dwarf will cool and fade. In more massive stars, the process may lead to the formation of neutron stars or black holes, but for a typical red giant, the end product is a white dwarf.
How would you know if the sun burned out?
it would be red , bigger , and and grow until it is a red giant , a red super giant , or a hyper-giant
What comes after a protostar?
After a protostar forms, it enters the next stage of stellar evolution known as the main sequence phase. During this phase, nuclear fusion begins in the core, converting hydrogen into helium and releasing energy that stabilizes the star. The star will remain in the main sequence phase for the majority of its life, with its duration depending on its mass. Eventually, when the hydrogen in the core is depleted, the star will evolve into either a red giant or supergiant, depending on its initial mass.
What are the stages of a medium sized star?
Protostar, Main Sequence, Red Giant, Super Nova, and the Neutron Star.
Which is a star in its old age Protostar Main sequence Black Hole or Red giant?
A red giant is a star in its old age. During this stage, a star expands and cools as it exhausts its hydrogen fuel. Eventually, it will shed its outer layers, forming a planetary nebula.
What is the life cycle of a yellow star?
Nebula protostar mid sized star red giant nova white dwarf black dwarf:)
Do red giant stars have lithium in their cores?
some, but not much. the principle componant of a red giant's core is helium. lithium is not a product of stellar nuclear reactions, so any lithium in a star would have been there from when the gas cloud collapsed into a protostar.
What are some differences between black and panda bears?
pandas (both giant and red) are smaller than the black bear. sorry if this doesnt help.
What is the diffrance between a white dwarf and a red giant?

What are the similarities between the sun and red giant?
Our Sun will eventually become a Red Giant towards the end of its life.

What are the stages of the stars life?
Nebula- protostar- Main Sequence Main Sequence- Red Giant- planetary nubula- white dwarf- black dwarf Main Sequence- Red Supergiant- supernova explosion- Nuetron star or a black hole
How did giant pandas get their names?
They are called giant pandas to reduce confusion between giant pandas and red pandas. they are considerably large compared to red pandas therefore making them giant
What are the stages of a stars life?
nebula then protosar then red dwarf, yellow star or a blue giant then a red giant then a red super giant then eithr a white dwarf or a supernova from the supernova a black hole or a neutron star if it is a white dwarf it turns into a black dwarf then a black holeNebulaBaby starStarGiant or supergiantWhite dwarfBlack dwarf
