Researchers Discover a Star's Minimum Possible Mass

paulmac84 writes "Stars that don't have enough mass never shine, dying billions of years before their bigger counterparts. But astronomers have never been able to measure the exact mass limit, because the lightest stars that do shine can be simply too faint to detect. Now, new images show for the first time how big a star must be to avoid impending doom. The long-awaited new images finally lay this question to rest, say the authors. The dimmest stars were measured as being 8.3% of the Sun's mass. All protostars that are smaller than this are headed for life as a brown dwarf."

    So apparently Orson Welles - even at his heaviest - was still too "lightweight" to be a real star.

    Ironic.

    The highest possible ego mass for a star must be Francis Ford Coppola then ... or did it collapse under its own weight?

    what makes a brown dwarf "brown"?
    Two possible reasons:
    1. It's scared shitless of larger stars.
    2. Suntan lotion.
    Also, the politically-correct term for them is "dwarves of color", er, "short stars of color", uh, "stars of color of diminutive ...", ah, ah, "vertically challenged stars of color".
    Yeah, that's it, "vertically challenged stars of color".
