How is the sun different from a white dwarf?

Answer 1

A Wolf Rayet is a star greater than 20 Suns which is loosing mass very rapidly.

A white dwarf is generally the remains of a star about the size of our Sun that has used up all of it's available hydrogen and is cooling slowly.

Answer 2

A red dwarf is simply a main sequence star that has a low mass, resulting a slow rate of fusion and a low luminosity. A brown dwarf is essentially a failed star without enough mass for nuclear fusion. Brown dwarfs may ignite deuterium fusion but cannot sustain it. Brown dwarfs can be thought of as intermediate between stars and gas planets. A blue dwarf is a hypothetical class of star that develops when a red dwarf consumes most of its hydrogen fuel and undergoes an increase in surface temperature, thus becoming bluer. Since red dwarfs consume their fuel so slowly the universe is not old enough for any blue dwarfs to have formed yet. A white dwarf is the dense remnant of a low to medium mass star in which fusion has stopped after the fuel was exhausted. White dwarfs glow with from their leftover heat.

Answer 3

The sun is a main sequence star that fuses hydrogen into helium in its core, while a white dwarf is the remnant core of a dead star that has exhausted its nuclear fuel and collapsed. The sun is much larger and hotter than a white dwarf, which is smaller, denser, and cooler.

Answer 4

The sun is brighter and has a very big number in temperature. A white dwarf has been part of a collapsed star that doesn't have heat and won't reach the stage of a neutron star or black hole.

Answer 5

No relationship whatsoever, except that both are classified as "stars". For a start, a white dwarf has stopped producing energy - it has no more fuel for nuclear fusion.
