WebFusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy. Thus fusion has the potential to be an inexhaustible source of energy. WebFor a star to transition to a red giant, it must possess a mass between one-half to eight times the mass of our Sun; astronomers term these stars low or intermediate mass. Nuclear fusion is the process by which two atoms combine to form a larger one. This process occurs in a star’s core, where hydrogen atoms are combined to form helium. WebLow-mass stars turn into planetary nebulae towards the end of their red giant phase. At that point the star becomes highly unstable and starts to pulsate. This produces strong stellar winds which throw off the outer layers of the star. The outer layers drift away from the star leaving a small hot, bright core behind, called a white dwarf.

WebMay 7, 2015 · After the outer layers of the star have swollen into a red supergiant (i.e., a very big red giant), the core begins to yield to gravity and starts to shrink. As it shrinks, it grows … A red giant is a star that has exhausted the supply of hydrogen in its core and has begun thermonuclear fusion of hydrogen in a shell surrounding the core. They have radii tens to hundreds of times larger than that of the Sun. However, their outer envelope is lower in temperature, giving them a yellowish-orange hue. Despite the lower energy density of their envelope, red giants are many times …
