Real life 'Death Star' observed destroying planets in its own solar system

Stars shine by converting hydrogen into helium through nuclear fusion. Once a star exhausts its nuclear fuel, it expands into a red giant, which can convert helium into carbon. When helium is depleted, the red giant contracts into a white dwarf, a dense remnant of the star's core. The gravitational pull of a white dwarf is strong enough to disrupt nearby planets. Changes in a star's mass can alter its orbit, potentially causing planets to move closer and be torn apart by the white dwarf's gravity.
