Main Sequence Star Death:After a low mass star like the Sun over fatigues the supply of hydrogen in its core, there is no longer any remains of heat to support the core against gravity. The hydrogen burning perdures in a shell around the middle and the star derives into a red giant. When the Sun transforms into a red giant, its atmosphere will envelope the Earth and our planet will be consumed in a fiery death. A star will eventually use up most of it's hydrogen and only be left with helium. This will cause pressure to crush down on the star to create a nuclear reaction using helium. Nuclear reactions culminate inside of the star, and because there is no longer any exterior push from fusion, the star begins to condense upon its self. This is the time in the cycle where the star leaves the main sequence. This collapse begins to build more and more pressure inside of the star until it is commensurable to have the fusing process of helium begin in the inside of the star, while some of the excess hydrogen incinerate just on the outskirts of the star. The artifact of this helium burning is carbon and oxygen. The star moves up, and depending on its size, either becomes a red giant or a red supergiant. After this time, the red giant is made up of mostly carbon. The next process of the cycle would be to solder the carbon into iron. The problem with this star is that there is not enough pressure in the core to begin this process. Because the exterior pressure of energy is no longer being maintained, the core collapses and sends shockwaves outwards, and the star's outer layers are sent out in a planetary nebula. The remains then turn into what is known as a white dwarf. The core of the dwarf is made up of mostly carbon (like coal), and has a white like glow as it still possesses a lot of left-over heat. The white dwarf now acquires much less mass because it has emitted its outer layers. The white dwarf is consecrated to drift in space for millennia as it slowly cools. Most whited dwarfs have an approximated size of the Earth (8,000 km diameter), and has a density of the weight of an elephant. It has a maximum weight of 1.4 solar masses. As it cools, it will begin to grow dimmer, and will eventually become a black dwarf - a frozen lump of carbon floating though space.
