Dec 13, 2015 · the smaller the starting mass of a star is, the longer it will live In the clouds of dust and gases, nebula. Hydrogen atoms forms a spinning cloud of gas and eventually pulls more hydrogen gas to the spinning cloud. As it spins, hydrogen atoms start to collide with each other and hydrogen gas heats up. When this reaches 15,000,000^@C nuclear fusion begins and …

Oct 13, 2017 · Described below are the 6 stages of how a star of about one Solar Mass forms. Stage 1 - Giant molecular cloud: A star begins life as a large cloud of gas. A region of high density within this cloud condenses into a huge globule of gas and dust and contracts under its own gravity. Stage 2 - Protostar: A region of condensing matter begins to heat up and starts to glow …

Oct 26, 2016 · It affects the lifespan and the life stages. A star needs mass to function so they must be relatively big to produce fusion and to keep from imploding. Smaller stars live longer since they need less fuel to stay stable and they will collapse to white then black dwarves at the end of their life. Massive stars with more mass require more fusion to remain stable and use …

Jun 29, 2016 · Sun stars it life from a huge cloud of gas hydrogen and dust called nebula. Due to gravity more mass of gases are accumulated in one place it become a proto star.and when it reaches huge size temperature and pressure inside increases. When temperature is about 15 million deg c nuclear fusion starts and a star is formed. increases stage is called main …

Apr 5, 2016 · Nebula .Proto star.main sequence.Red giant.White dwarf. Stars form from a huge cloud of gas and dust known as nebula. When mass increases due to gravity the temperature and pressure at center goes up.When it reaches about 15 million degree c hydrogen fusion stars..After main sequence when hydrogen is finished the star become red giant and puff out gases.White …

Nov 18, 2015 · The Stage in which it burns hydrogen to helium. The Star remains the longest in the stage when it is burning Hydrogen into Helium. For our Sun this is called the main sequence stage which will last for about 4.5 Billion years more , this depends on how fast the star is burning up fuel. For more massive stars this stage lasts for a few hundred million years. That's why …

May 31, 2016 · The average star, like our own, turns into a white dwarf. Average Star. White Dwarf. A massive star becomes either a neutron star or black hole.

The age of the star. As the star reaches a certain point in its life cycle, it runs out of hydrogen, which is basically the star's fuel for nuclear fusion. (Nuclear fusion is the process of combining smaller atoms into larger ones. In this case, hydrogen is fused into helium, which causes the sun to release so much energy. The heat doesn't cause the star to expand because of the …

Mar 15, 2016 · The Rate of fuel consumption and the Final Stage. There isn't much of a difference in the initial stages of Stellar Evolution, the only difference is the rate at which the fuel burns. Both, a low mass Star and a High mass Star will Start off with fusing hydrogen into Helium, though a high mass Star will burn it faster because of increased pressure and temperature in the core. …

Dec 7, 2016 · About half a billion years longer till it dies. Vega’s distinctly blue color indicates a surface temperature of nearly 17,000 degrees F, making it about 7,000 degrees hotter than our sun. Roughly 2.5 times the diameter of the sun, and just less than that in mass, Vega’s internal pressures and temperatures are far greater than our sun, making it burn its fuel faster. This …
