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.
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
When matter is pulled into a protostar, it heats up and increases in density. This process leads to the formation of a protostar as gravitational forces pull matter towards the center, eventually igniting nuclear fusion and forming a stable star.
To see images of a protostar, one would go inside a Bok Globule. This might be hard to do, considering the fact that a protostar is the gas of a giant molecular cloud. But hey, if you can get there, it'd be a sight to see!
A protostar becomes balanced when the gravitational forces pulling matter inward are balanced by the outward pressure due to nuclear fusion at its core. This marks the transition from a contracting protostar to a stable star in the main sequence phase of its lifecycle.
A protostar is supported against gravitational collapse by the outward pressure generated from the heat produced by gravitational contraction. This pressure, known as radiation pressure, acts to counterbalance the force of gravity pulling the protostar inward. As the protostar continues to contract, it eventually reaches a point where nuclear fusion ignites in its core, providing an additional outward pressure that stabilizes the star against collapse.
No one. It comes from the Greek - proto - meaning first. So first star - a protostar.
The stage that comes after the nebula in the star's life cycle is the protostar stage. During this stage, gravity causes the gas and dust within the nebula to clump together and heat up, eventually forming a dense, hot core. This marks the beginning of nuclear fusion within the protostar.
Mostly hydrogen (with some helium, deuterium, and lithium). Other elements (all other elements) are added as the date of formation of the protostar comes closer to the current date.
A Protostar.
A protostar takes about 100,000 years to reach the main sequence.
A protostar is more like a stage previous to a star - before it ignites.
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
No. The sun was a protostar about 4.6 billion years ago.
the color of the protostar is red
Apparently someone not paying ATTENTION.
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
No one
