Is Enceladus a Comet? a Cometary Perspective
Introduction: The discovery of icy plumes emanating from Saturn's moon Enceladus by the Cassini spacecraft has raised questions about the cometary nature of this small satellite. The release of gas and dust from cometary nuclei is restricted to " jets " or plumes also and this activity has been observed in comets at distances much further than Saturn's orbit, including comet-like activity and a...
متن کاملStirring unmagnetized plasma.
A new concept for spinning unmagnetized plasma is demonstrated experimentally. Plasma is confined by an axisymmetric multicusp magnetic field and biased cathodes are used to drive currents and impart a torque in the magnetized edge. Measurements show that flow viscously couples momentum from the magnetized edge (where the plasma viscosity is small) into the unmagnetized core (where the viscosit...
متن کاملDialysis with Stirring
Substances to be purified by dialysis are placed in collodion bags together with a toy "marble" or a bubble of air. The bags are stoppered and placed in glass tubes of a rocking machine. Distilled water of the desired temperature is circulated through the tubes (around the bags) at a rate of about 8 cc. per minute per bag while the machine is in motion. The rolling of the marbles or bubbles cau...
متن کاملStirring a Bose–Einstein condensate
By shining a tightly focused laser light on a Bose–Einstein condensate (BEC) and moving the centre of the beam along a spiral path one may stir the BEC and create vortices. It is shown that one can induce rotation of the BEC in the direction opposite to the direction of stirring. When a spoon, stick or another object of a similar shape is used to stir a liquid, the liquid rotates in the directi...
