The Cosmic Fondue

What have White Dwarfs, Neutron Stars, and Black Holes in common? – Accretion disks! For a Swiss who has stirred cheese in multiple occasions and settings, a direct comparison to fork-induced cheese swirls seems obvious. As Alexandra Veledina from University of Turku in Finland points out, the spinning matter of the two might look similar but the physics involved are fundamentally different. Veledina was one of the lead conveners of the ISSI Workshop on Accretion Disks bringing together more than thirty international experts to discuss and sharpen our understanding about them that we developed over the past fifty years.
