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.
This stage is called protostar formation. As the nebula collapses due to gravity, it begins to spin faster and forms a hot, dense core known as a protostar. This marks the beginning of the process that will eventually lead to the formation of a new star.
When the gas in the nebula's center stopped collapsing, it likely reached a stable equilibrium where the inward force of gravity was balanced by the outward pressure from nuclear fusion or other energy sources. This equilibrium could result in the formation of a protostar or a star, depending on the mass and composition of the gas.
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
Plasmolysis is the reason because it always has water to keep it full.
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.
The pressure within a protostar counters gravity and prevents the star from collapsing further.
The uterus keeps the trachea from collapsing in a fetal pig.
Its cytoplasm.
Jets and magnetic fields can have significant effects on a protostar. Jets can help remove angular momentum from the collapsing protostar, allowing it to continue collapsing and forming a star. Magnetic fields can also impact the accretion process by channeling material onto the protostar's surface in specific regions, affecting its growth and evolution. Additionally, the interaction between jets and magnetic fields can influence the star's formation and its surrounding environment.
cytoplasm
As gravity collapses the cloud to form a protostar, the temperature and luminosity both increase. The increase in temperature is due to the compression of material, causing the protostar to heat up as energy is released. The increase in luminosity is a result of the protostar radiating this energy.
This stage is called protostar formation. As the nebula collapses due to gravity, it begins to spin faster and forms a hot, dense core known as a protostar. This marks the beginning of the process that will eventually lead to the formation of a new star.
A star is called a protostar before it begins nuclear fusion in its core and officially becomes a star. During this stage, a protostar is formed from a collapsing cloud of gas and dust, as gravity pulls material together and heats up the core.
A protostar is the first part in the birth of a star. It's age, relative to itself is very young, anywhere between 0 and 100,000 years.

The trachea has a series of cartilage rings that prevent it from collapsing.
