🌌 Some cosmic objects exist at the threshold. Too massive for planetary peace, too small for stellar fire, they drift through ages in slow surrender to darkness. ✍️ Discover these failed stars between worlds 🔭: https://TPC8.short.gy/OdqAD
Two failed stars given a second chance. This is the first mass transfer process seen in a brown dwarf pairing ever discovered. Go, go, my brown little stars. ..., a team of scientists has discovered a tightly orbiting pair of brown dwarfs t
If we're calling Brown Dwarfs 'Failed Stars' and 'Substellar objects' then perhaps it makes more sense to call this Jupiter sized object a 'planet' rather than a 'moon' There's every chance the Gas Giant has moons as well... https://www.sci
What “browndwarfs” means
WikipediaBrown dwarfs are substellar objects that have more mass than the biggest gas giant planets, but less than the least massive main-sequence stars. Their mass is approximately 13 to 80 times that of Jupiter (MJ)—not big enough to sustain nuclear fusion of hydrogen into helium in their cores, but massive enough to emit some light and heat from deuterium fusion, 2H, an isotope of hydrogen with a neutron as well as a proton, that can undergo fusion at lower temperatures. The most massive ones can fuse
