Abstract
Vortex shedding from a microsphere oscillating in superfluid He-4 at mK temperatures is compared with that from a laser beam moving in a Bose-Einstein condensate as observed by other authors. In particular, in either case a linear dependence of the shedding frequency f(v) on Delta(v) = v - v(c) is observed, where v is the velocity amplitude of the sphere or the constant velocity of the laser beam ...
