Sentences with phrase «measuring gas motion»

Measuring gas motion by the Doppler Effect is one of the techniques in radio astronomy.

«The VLTI is the only facility that can directly measure the gas motions in the extended atmosphere of Antares — a crucial step towards clarifying this problem.The next challenge is to identify what's driving the turbulent motions.»

Not exact matches

As described in a Science paper, astronomers measured the motion of gas to a distance approximately 5.5 times the event horizon radius.

We have created the most complete compilation so far of published measurements of the motion of gas and stars in the Milky Way, and compared the measured rotation speed with that expected under the assumption that only luminous matter exists in the Galaxy.

Scientists can measure temperature, pressure and gas motions when they study the signature of molecules in the signals they detect.

Because the molecules emit radio waves at specific frequencies, shifts in those frequencies caused by motions (called Doppler Shift) can be measured, revealing the direction in which the gas is moving relative to Earth.

If you make the parcels of gas small enough, then you reach a scale where «temperature» as an average measure of energy breaks down, where the tiny parcels of gas are constantly «heating» or «cooling» a tiny bit in the sense that the volume in question gains or loses a bit of energy during the random motion of the molecules.

Note that temperature of a gas is a measure of translational motion ONLY.
