Do you often read astronomy articles and get confused by some terms introduced ? Here are the few Major Ones Hydrogen Fusing All the stars possess hydrogen in their cores which fuses to helium and provides energy(heat) which creates outward pressure which prevents star from collapsing due to its own gravity(due to mass). Red Giant When all of the hydrogen burns to helium and the balance of the fusion energy and gravity doesn’t remain and gravity and gravity takes the edge and starts contracting the star , then heat builds up inside the star’s core and the little hydrogen fuses to helium. This ignition of hydrogen expands the outer layer of the star and it grows bigger and takes the name of Red Giant(big enough to swallow mercury) Red Giant Triple Alpha process A reaction that takes place in the core of red giant when the helium gets converted(burned) to carbon He(4) + He(4) à Be(8) + gamma rays Be(8) + He(4) à C(12) + gamma rays Binary Systems Binary symbolizes two star...
Wanna Know one of the heaviest element around the space? The White Dwarf Birth All large mass stars collapse either to black hole or take a path through neutron star to black hole. But the medium & small stars have a different phenomenon. Suppose our sun(medium sized star in comparison to other stars) has hydrogen within it’s layers i.e the core. Sun's Internal As the temperature is extremely hot in the core so hydrogen fuses to helium which further increases the temperature and pressure builds up which opposes the gravitational force that is pushing the star from the outer layer to collapse it. These two forces (the pressure(force) from inside and the outer gravitational force) balance each other and star maintains it’s size. Now when the Sun uses up all the hydrogen by burning it to helium , the temperature decreases which results in decreasing the pressure which pushes the star outward , and gravitational force takes the edge and star starts collapsing. When the star gets...
