    Did you even read that page you linked to? Right at the top, it says:

    They are a mix of brown dwarfs and planetary-mass objects.

        “Y dwarf stars” are not even a thing!

        Neither brown dwarfs nor planetary-mass objects are stars.

        Are you just a troll?

          They are!

          Electromagnetically and gravitationally and chemically they act like stars.

          Gas giant simulations are often performed by stellar codes such as mesa. Stellar physics and stellar simulations with fusion turned off. Morphologically, they are stars. We should move on from the cold war brain’s fusion chauvinism.

          They are fundamentally different objects than planets. They have their own planetary systems. They’re stars, just unlit.

          Juno gravity results imply Jupiter’s core is dissolved hydrogen plasma sludge, also known as the dilute core model. Kronoseismology (using saturn’s rings as a seismograph; Cassini read it like a DVD) implies the same is likely true for Saturn due to the discovery of g-mode waves mixing with the f-mode signal detected by ring occultations.

            I wandered in here from computer science, and I’m going back to solving parallel cache coherency for a bit of light relief.
