what is the first stage of stars?

Answer 1

Stars from from large clouds of gas and dust. When the cloud cools enough, it can begin to gravitationally collapse. As the cloud collapses it begins to rotate. The dense clump of gas in the center gets hotter and hotter and denser and denser, until it can begin to fuse 4 Hydrogens into a Helium. This is point is defined as the birth of a star, because the fusion ( nuclear fusion) releases enormous amounts of energy and the star is said to reach main sequience. Energy escaping the star is what we observe as light.

However the outside of a star is still gonna be surrounded by cloud of gas and dust called cocoon nebula. Eventually the gas and dust will be either sucked up by the star, ejected out of the new solar system or will form planets.

Here is a photo of a protoplanetary disk, a dense cloud from which a star will eventually form from:

Does that make sense

Answer 2

An interstellar cloud of dust and gas, which becomes unstable and begins to collapse under its own gravity. Radiation gets trapped in the cloud, causing the temperature to rise. Thus it becomes a protostar, continuing to heat up and become more dense. This is when it begins to resemble a star. Once the core heats up enough to ignite nuclear fusion of hydrogen into helium, about 10,000,000 degrees Kelvin, it reaches hydrostatic equilibrium, and a star is born. In a nutshell.
A white dwarf is the end of a star's lifetime.

Answer 3

A proto star is the first stage prior to fusion ignition. A cloud of hydrogen gas that has begun to collapse into a dense ball of super heated plasma. They are visible in infrared due to their high heat.

Answer 4

collecting the dusts

Answer 5

i belive a white dwarf

Answer 6

a small atoms
