It occurs whenever
a supersonic stream of fluid, such as hot gas from a forming star, strikes an obstacle, such as older, slower - moving gas, in its path.
The Sun continuously emits
a supersonic stream of particles, at such high temperatures that the atoms are broken up into a plasma of ions and electrons.
«The first thing we detected is
a supersonic stream emerging from the star forming inside the ionized gas region.
Not exact matches
Saturn's storms are, surprisingly, more powerful than Jupiter's, and its
supersonic jet
streams are much faster.
But while they're good at predicting
supersonic sound sources, they have a hard time predicting all the components of subsonic jet noise, especially in the sideline direction, or perpendicular to the exhaust
stream.
Even though it was estimated that there are 56 solar masses in the disk, compared to 15 solar masses in the central star, the disk's rotation is perfectly aligned with the
stream of ionized gas, suggesting that the
supersonic gas
stream is being accelerated and aligned from an accretion disk.
