[QUOTE="Channel Hopper, post: 1091633, member: 175144"] Rather than sunspots, the money last year was ejected silicates forming a cloud around Betelgeuse, though it would have to be a huge amount to cause such dimming. The 'spots' could also be large lumps of heavier elements depositing on the surface, a precursor to a supernova on a giant star before the collapse of the core. It was also suggested years ago that Betelgeuse was a binary or possibly multiple star system, with the circumstellar clouding being the remnants of the partner(s) after their demise. [/QUOTE]
