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.
When a protostar rises to 10000000 degrees celsius will a protostar become a star before or after nuclear fusion?
A protostar must reach about 10 million degrees Celsius for nuclear fusion to start in its core, triggering the transition into a true star. This marks the point where hydrogen atoms begin fusing into helium, releasing energy in the process. So, a protostar will become a full-fledged star after nuclear fusion begins at this temperature.
What is happening to the star of a protostar?
A protostar is a star that is just beginning to form out of a stellar nebular (under gravity). The core of the gravitational collapse is getting more and more massive and is heating up as a result of the gravimetric contraction but has not yet reached the point where nucleosynthesis has begun in its core. It is when this happens that it becomes a star.
What is the study of evolution from a genetic point of view?
The study of evolution from a genetic point of view is known as evolutionary genetics. It focuses on how genetic variation within populations changes over time, leading to the evolution of new species. By studying genes and their interactions, evolutionary geneticists can uncover mechanisms driving evolution.
Is a proto star bigger than a star?
Short answer: YesThe latin root "proto-" means early, or earliest. As a star is an approximately spherical mass of matter undergoing a fusion/fission reaction due to the enormous pressures created at the center of the star due to its massive density. By this logic, we know that a protostar or "early star" is something which isn't yet, but will become a star in the future. By observing the universe and understanding the composition of stars, we've theorized that stars (and their solar systems) are usually formed by nebulae. As the nebulous cloud condenses under its own gravitational pull. Eventually the density reaches a point where the fission/fusion reaction can occur. So it follows that the nebula, is less dense (and by requirement), more voluminous. So a protostar takes up a much greater space, and would appear larger, but it would be less dense. We also have to remember that the size of stars varies. You could compare one protostar to another existing star, but the comparison wouldn't tell you anything about the relative sizes of the two different objects. IE: a big star would've been an even bigger protostar, and a small star would have been a smaller protostar.

Does the theory of Evolution disprove the concept of reincarnation?
Evolution was the starting point for Reincarnation.
What defines the bodys set point?
the level or point at which a variable physiological state tends to stabilize is called set point.
What size is a protostar?
Protostars can be a mix of colors usually orange, red ,purple , blue, and yellow.

Helps to stabilize the origin of the prime mover?
The fixator of a muscle stabilizes the muscle at the point of origin.
What is a star is a baby what is it called?
A star is often referred to as a "protostar" during its early formation stage. This occurs when gas and dust in a molecular cloud collapse under gravity, leading to the accumulation of material that heats up and begins to form a new star. As the protostar continues to gather mass and temperature rises, it eventually reaches the point of nuclear fusion, at which point it becomes a main-sequence star.
Does evolution have a point?
Nope. Unless you really want there to be one.
Where does a cycle of a star begin?
Stars usually begin their lives in stellar nurseries: (relatively) dense clouds of interstellar gases. Critical densities may be achieved when nearby stars go nova, at which time pockets in the nebula collapse under their own weight to form a protostar. If the mass of the protostar is sufficient, further gravitational collapse will cause the temperature and pressure in the core to rise to the point where hydrogen starts to fuse. At that point, a star is born.
What is operating point instability and need of stabilization?
A: And system or amplifier may have instability as some point due to external or internal function therefore intervention is needed to stabilize the system at that particular point of operation.
During the t-tauri phase of a protostar, what changes occur in its structure and behavior?
During the T-Tauri phase of a protostar, it undergoes significant changes in its structure and behavior. The protostar becomes more stable and begins to generate its own energy through nuclear fusion. It also develops a strong magnetic field and may exhibit intense solar flares. Additionally, the protostar starts to clear out the surrounding gas and dust, paving the way for the formation of a planetary system.
