A mystery companion planetoid forms a binary system with a brown dwarf, located 460 light-years away in Taurus. The object is too small to be another brown dwarf, too young to have formed by accretion, and heavier than most planets - but too light for nuclear fusion. The object's mass is between 5-10 Jupiters, making it too small to fuse deuterium. The International Astronomical Union uses 13 Jupiter masses as the threshold for fusion. Yet look a the image. There is clearly a subdued glow in the sphere to the right of the dwarf - as evidence by the few lit pixels, which could not possibly have been caused reflection from the brown dwarf, or heating from the dwarf due to its rotation in front of that star and great distance. Since the glow cannot be evidence of hot fusion, a few vorticians may be led to wonder - what about LENR? or fractional hydrogen as the source?
