A protostar compresses primarily due to the gravitational attraction of its accumulating mass from the surrounding molecular cloud. As material falls inward, it gains kinetic energy, which increases the temperature and pressure at the core. This process continues until the conditions are sufficient for nuclear fusion to ignite, marking the transition from a protostar to a main-sequence star. The ongoing gravitational collapse is balanced by thermal pressure from the rising temperature, creating a dynamic equilibrium within the protostar.
What else can I help you with?
Do prostars become stars?
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
What happens when matter is pulled into a protostar?
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.
Where could one go to see images of a protostar?
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!
When does the protostar become balanced?
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.
What keeps a protostar from collapsing?
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.
The earliest stage of a stars life is called a?
A Protostar.
What is the life span of protostar?
A protostar takes about 100,000 years to reach the main sequence.
Are protostar a star?
A protostar is more like a stage previous to a star - before it ignites.
Do prostars become stars?
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
Was the Sun a protostar about a million years ago?
No. The sun was a protostar about 4.6 billion years ago.
What is the temperature of a protostar?
the color of the protostar is red
Who the heck thinks the question what is a protostar means what does a protostar look like?
Apparently someone not paying ATTENTION.
Who named the protostar and why?
No one. It comes from the Greek - proto - meaning first. So first star - a protostar.
What is a binary protostar?
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
Who went to a protostar?
No one
What slow down the contracting of a star forming cloud when it makes a protostar?
trapping of thermal energy inside the protostar
Will a protostar form near the end of a star's life cycle?
No, a protostar is basically the BEGINNING of a star's life cycle.
