How a stable star is formed
Web7 de mai. de 2015 · Fusion continues in red supergiants until iron is formed. Unlike the elements before it, iron releases no energy when fused. This is because iron has the most stable nucleus of all the elements. Elements lighter than iron generally emit energy if fused, since they move from a less stable nuclear structure to a more stable one. Webenergy is released and radiates outwards. A star, like the Sun, in its main sequence period, is stable - gravity tries to pull it inwards, and radiation pressure from the nuclear reactions...

Webcooler. The most abundant element in the Sun is hydrogen. True. The proton-proton chain releases energy because mass is created in the process. False. Neutrinos have never been detected experimentally. False. The density and temperature in the solar corona are much higher than in the photosphere. False. WebThose stars have [Fe/H] values no larger than −1.5 and sometimes as low as −3.5. Called metallicity, [Fe/H] indicates the overall abundance of elements beyond hydrogen and helium, up to and including iron. Also, r-I and r-II stars presumably formed early in cosmic history, whereas the solar system is a relatively youthful 4.6 billion years old.
Web5 de mar. de 2015 · Technically, the tempretures necessary for star formation is directly proportional to the general heaviness of the atoms in the gas cloud forming it. in other words, stars can be formed out of any kind of atom, notwithstanding how metallic it is, as long as They can reach the high enough temperatures necessary to begin fusion.
