    Star Life and Death – National Radio …

    • Different star types “live” and “die” in different ways based on how much matter they started with and if they were born with siblings nearby. The color of a star is an indicator of its temperature. The cooler stars a… See more

    Life and Death of Brown Dwarfs

    Brown dwarfs are barely stars, as they only shine for about ten million years while their cores crush the rare element deuterium into helium. After their deuterium is gone, brown dwarfs glo… See more

    Life and Death of Dwarf Stars

    Red, orange, and yellow dwarf stars can keep up the tug-of-war — gravity squeezing inward against a fusing core shining outward — for billions of years. Their insides tum… See more

    White Dwarf

    A hot core of carbon atoms holds together, thanks to gravity, but resists crushing itself, thanks to the pressure of the spaces inside the atoms. If you’ve ever tried to squeeze a balloon, tha… See more

    Death of Giant Stars

    Giant stars range from about 3 times the mass of our Sun up to the hypergiants, which can be a 100 times the Sun’s mass. The core of a giant star is under extreme and consta… See more

    Are brown dwarfs a failed star?
    However, they never pull in enough material to start nuclear fusion; instead, they slowly contract, cool, and glow in the infrared from the release of gravitational energy, like Jupiter. Eventually, they simply fade away. Some people think of brown dwarfs as failed stars.
