contraction | A mass motion towards the center of gravity of a celestial body | mass motion | |||||||
convection | A mass motion in a circulatory pattern. Process in the Sun (and possibly other stars) perhaps caused by solar rotation, which produces the immensely powerful electrical and magnetic fields associated with sunspots. | mass motion | |||||||
ergodic motion | Motion by one or more particles which fills phase space with uniform density after a sufficiently long time. | mass motion | |||||||
expansion | mass motion | ||||||||
galaxy motion | mass motion | ||||||||
hydrodynamic soliton | A finite-amplitude disturbance which is propagated through a fluid without any change of shape. MHD solitons are also known. | mass motion | |||||||
merger | mass motion | ||||||||
meridional flow | Flow between the poles, or between the equator and the poles. A positive value indicates flow away from the equator: a negative value, flow toward the equator. | mass motion | |||||||
solar motion | length per unit time | The velocity of the Sun through space, relative to the local standard of rest. The solar motion is U = -9 kilometers per second, V = +12 kilometers per second, and W = +7 kilometers per second. | peculiar velocity | ||||||
sound wave in gas | A longitudinal wave propagated through a gas as a pattern of alternating high and low pressure. | periodic motion | mass motion |
