A white dwarf is a type of dwarf star. These stars are created when a small or medium-sized star reaches the end of its life. Over billions of years, as they cool down significantly, they eventually cease to emit any observable light or heat, transforming into what is known as a black dwarf.
Using precognition, Darth Vader steered the Chimaera so that it would arrive at the Grysk operational base before the Grysk themselves. During this, he noticed a white dwarf star directly in their path and altered the ship's trajectory. Ardos represents another instance of a white dwarf within the galaxy.
