What two forces maintain hydrostatic equilibrium in a protostar?
In a protostar, hydrostatic equilibrium is maintained by the balance between gravitational forces and thermal pressure. Gravity pulls the material inward, causing the protostar to collapse, while thermal pressure, generated by nuclear fusion and the heat from the collapsing gas, pushes outward. When these two forces are in balance, the protostar can maintain a stable structure as it continues to evolve toward becoming a star.
What stage comes after nebula in the star stage?
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.
What comes first a Nebula or a protostar?
A nebula comes first; it is a large cloud of gas and dust in space. Under the influence of gravity, regions within the nebula can collapse to form a protostar. As the material falls inward, the protostar heats up and begins the process of nuclear fusion, eventually leading to the formation of a star.
Why did the nebula begin to shrink inward?
The nebula began to shrink inward due to gravitational forces. As particles within the nebula were pulled toward its center, the concentration of mass increased, leading to the formation of a protostar at the core. This marks the initial stage of a star's formation.
How are nebulae and stars related?
Nebulae are large clouds of dust and gas in space where stars are born. Within a nebula, gravitational forces can cause the gas and dust to collapse and form a protostar, which eventually ignites nuclear fusion and becomes a star. Therefore, nebulae are the birthplaces of stars, and stars are formed from the material within nebulae.

Why doesnt a protostar form a black hole?
The pressure within a protostar counters gravity and prevents the star from collapsing further.
What is a binary protostar?
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
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.
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 stage comes after nebula in the star stage?
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.
What is the process by which a protostar is heated up to initiate nuclear fusion and become a star?
A protostar is heated up by gravitational forces causing it to contract and increase in temperature. Once the core reaches a high enough temperature and pressure, nuclear fusion reactions begin, releasing energy and making the protostar shine as a star.
What does the word strongmen means?
The strong men are the two forces within.

The earliest stage of a stars life is called a?
A Protostar.
