Bizarre object hotter than the sun is orbiting a distant star at breakneck speed

A bizarre, super-hot celestial physique  is breaking data and difficult astronomers’ understanding of the boundary between stars and planets. 

The article, known as WD0032-317B, is a brown dwarf — a sort of shiny, gaseous “protostar”. Brown dwarves usually have the same atmospheric composition to Jupiter however are 13 to 80 occasions bigger. At that mass, these objects start to fuse hydrogen isotopes of their cores. Nevertheless, they are not fairly huge sufficient to spark the form of full self-sustaining stellar fusion that powers stars like our solar — consider smoldering charcoal quite than a lit wood-fired oven.
