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.
The temperature of a protostar increases over time due to gravitational contraction. As the protostar gathers mass from its surrounding dust and gas, gravitational forces compress the material, raising its temperature. This process continues until the core reaches sufficiently high temperatures for nuclear fusion to ignite, transitioning the protostar into a main-sequence star. Additionally, energy from the infall of material and the release of potential energy during contraction contribute to this increase in temperature.
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.
A protostar is more like a stage previous to a star - before it ignites.
A protostar takes about 100,000 years to reach the main sequence.
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.
No one. It comes from the Greek - proto - meaning first. So first star - a protostar.
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
No one
trapping of thermal energy inside the protostar
No, a protostar is basically the BEGINNING of a star's life cycle.
