What are the starting materials for a star?

Answer 1

A star is mainly up of hydrogen, and a little bit of helium. When those two clump together, they begin to have an enormous amount of gravity, pulling the hydrogen atoms close to the center of the star. The gathering of all these atoms in one place contributed to a very high temperature, and so much collision might allow two hydrogen atoms to form one helium atoms in a process called " Nuclear Fusion". Nuclear releases a lot of electrons into space (energy released), and these " shooting electrons" is what makes the star shine.

Answer 2

Stars are made from hydrogen. The stars shine because pressure of the mass of hydrogen, compressed by its own gravity, is enough to cause the hydrogen in the star to fuse, to turn the hydrogen into helium, with a little energy left over. It is that "energy left over" when the hydrogen fuses into helium that makes the stars shine.

Answer 3

The core of a star is the central part, which is the hottest part of that star. It contains gases in the form of highly heated plasma. For example, our Sun, has a surface temperature of approximately 6000 K, but its core is having a temperature of 15, 000, 000 K. Isn't that too hot !?

Answer 4

An object is considered a star if it is massive enough (around 80 times the mass of Jupiter) to undergo hydrogen fusion in it's core. Objects between about 13 and 80 times the mass of Jupiter, called brown dwarfs, blur the line between planet and star. They are massive enough to fuse deuterium (an isotope of hydrogen containing one proton and one neutron), but not large enough to fuse hydrogen.

Answer 5

Mostly hydrogen, but with a little bit of all the other material that's floating in that area of space.

Originally, everything was hydrogen except for a little bit of helium and a tiny trace of lithium left over after the Big Bang. But as stars formed and died, their supernova explosions scattered the heavy elements created during the supernova explosion back into space, and a little of that "supernova ash" went into forming the next generation of stars. After several generations, there were enough heavy elements scattered through space to form planets, like our own.

A star like the Sun probably formed with 90% hydrogen, 9% helium and 1% of "metals", which is everything heavier than helium. Most of the heavy elements went into the planets rather than to the Sun; we're not sure why, but it worked out well for us!

Answer 6

The starting materials for a star are mainly hydrogen and helium gas, which are the most abundant elements in the universe. These gases come together under the force of gravity to form a dense core where nuclear fusion reactions occur, leading to the birth of a star.

Answer 7

a ball of gases and nebula then is it goes into the stage of a protostar

Answer 8

The two big things that make up a star are helium and hydrogen

Answer 9

Hydrogen
