Stellar Evolution Death of a Star (size of the sun)
{"Image DocumentName": "Stellar Evolution Death of a Star (size of the sun)", "Image ImageDescription": "remain same size (main sequence) for billions of years because energy produced through fusion equals gravitational pull. hydrogen is used up so gravity takes over, which then produces heat by contraction. entire star expands (Red Giant) core temperature rises enough for helium to fuse into heavier elements, producing a carbon-oxygen core. surface gases are blown away, leaving core (white dwarf) planetary nebula- glowing halo of gases. fades as gases dissipate into space leaving white dwarf behind. once all fuel is used up, the core will no longer glow, becomes a black dwarf.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
