CO GAS INSIDE THE PROTOPLANETARY DISK CAVITY IN HD
... surface density. Also, such planet is expected to co-orbit with a corotation zone, which should carry significant amounts of gas (Armitage 2011). Thus, studying the gas surface density structure of transition disks is of direct importance to distinguish between different clearing and formation scena ...

Velocity-Ion Temperature Gradient Driven Modes
... Magnetically confined toroidal plasmas play a leading role in the pursuit of controlled thermonuclear fusion. The high energy densities required to yield reaction crosssections large enough to consistently fuse light elements are so great that the fusile atoms are ionized, creating a plasma. In orde ...

... Thus, in uniform circular motion there must be a net force to produce the centripetal acceleration. The centripetal force is the name given to the net force required to keep an object moving on a circular path. The direction of the centripetal force always points toward the center of the circle and ...
