xxx Supernova Explosion
Our sun will loose its outer material without supernova-explosion, also suns with the remaining mass till to 1,4 sun-masses after their time of burning. A sun with the remaining mass lower than 3,2 times mass of our sun will become a neutron- star, with more remaining mass become a black hole. Credits to physics.unr.ede
