White Dwarf Research Paper

The White Dwarf is what a star like the sun becomes after the star has worn of its nuclear fuel. Near the end of a star's nuclear burning stage, this kind of star will expel most, of its outer material, making a planetary nebula. The only thing that remains is the stars hot core. The core of the star is very hot, the core reaches up to a temperature of 100,000(179,540.33F) Kelvin. After a billion years or so the star will cool down. The planetary nebula is the outer layer that gets lost when the star is changings to a different star. A star is a luminous globe or ball of gas producing its own heat and light by nuclear reaction or nuclear fusion. The stars are born from nebulae and consist mostly of hydrogen and helium gas.

White dwarf stars have a mass similar to the Sun, but only 1% of the sun's diameter; close to the diameter of the earth. The temperature can get too 8000C or more, but being smaller than the sun is only has 1% of the sun's luminosity or less. The white dwarf are the shrunken remains of normal stars, whose nuclear energy supplies have all been used up. A White Dwarf Star is a low or medium mass star the mass is less than about 8 times the mass of the sun. A typical White dwarf star is about the mass of the sun yet slightly bigger than earth. The first white dwarf discovered was the Sirius B, discovered in 1862. The White Dwarf Star is a very faint light. The star is the average size of the sun but no larger than Earth. The material in a white dwarf star no longer undergoes fusion reactions, so the star no longer has energy. A white dwarf is what stars like the sun become after their nuclear fusion. Near the end of the stage this star has expelled all of its outer material. This then creates a planetary nebula. Only thing that is left is the core. The nearest star known from earth is Sirius B. This star is 8.6 light years away. There a currently 8 white dwarfs nearest to the sun. Sirius is smaller than earth and has much denser gravity. The brightest ness of this star is
