Formation of Brown Dwarf

Formation of Brown Dwarf 463-brown-dwarf-forming-dixon – A brown dwarf star shines within its accretion disk. Streams of ionized dust and gas are drawn to the forming star by its magnetic field. A detailed astronomical illustration depicting a young protostar undergoing magnetospheric accretion within a dense stellar nursery. The central, turbulent orange protostar is surrounded by a massive, glowing circumstellar disk of dust and gas, with small planetesimal fragments orbiting in the dark foreground. Powerful magnetic field lines pull material out of the inner disk, funneling it onto the stellar surface in bright, energetic impact streams, while high-velocity blue gas jets erupt outward along the rotational poles into a backdrop of cosmic nebulae.
