    Default big planets may form the same way stars do



    another indication that Nature is richer than Man imagines....

    A Four-Star Lightweight

    note that since the lightest member of the system is only ~10 Mjupiter it's too light to be a brown dwarf (>13Mj)

    Nice find, not_Fritz! I've wondered about this myself, given the blurred lines between high mass gas giant and a low mass brown dwarf. I appreciate the good read, sir!

    Gassy giants and dirty brown dwarves. Sounds like the seedy side of Tolkien.

    Interesting for sure, but... Is anyone surprised? People are really good at making categories and trying to put everything in its proper box. I think this has provided us many great advanced via reductionism, but it blinds us to similarities as well.

    If you consider a binary formation, can one draw a stark line between a binary star pair, a star & brown dwarf, or a star and giant planet? In reality, there is a continuum of process from a double supergiant system and a pair of failed brown dwarfs. I don't even see a real line between star formation and planet formation, for certain values of scale and ignoring a difference in materials.

    The continuum is a fundamental concept of calculus, and applies to everything from the vacuum energy to evolution. Very few related processes have step-functions built into them. I am quite sure there are a huge number of failed star collapses that resulted in something that looks like the Jovian system all on its own, drifting in space just as our solar system does.

    So, cool observation, definitely, and a good read, but it just says to me that all is working as expected.
    Okay, I'll stop with the my philosophy of science soapbox now. You're probably wondering why I'm prattling on about this anyway. Sorry...

    I see no reason why Nature needs to observe the artifice of human linguistic conventions. So I think we are in violent agreement.

    So, cool observation, definitely, and a good read, but it just says to me that all is working as expected.
