Sentences with phrase «turbulent motions»

It is thought that the energy necessary to heat the corona is provided by turbulent motion in the convection zone below the photosphere, and two main mechanisms have been proposed to explain coronal heating.

It is generated by turbulent motions of liquid iron in Earth's core.

The data enabled the researchers to show that turbulent motion increases the fluid's ability to conduct electricity and therefore amplifies the magnetic field, rather than reducing it as earlier experiments had appeared to show.

Recent computer simulations have shown how hundreds of jets can act as hypersonic swizzle sticks stirring a cluster's gas into turbulent motion that inhibits new stars from forming.

«With CH +, we learn that energy is stored within vast galaxy - sized winds and ends up as turbulent motions in previously unseen reservoirs of cold gas surrounding the galaxy,» said Falgarone, who is lead author of the new paper.

Since CH + forms exclusively in small areas where turbulent motions of gas dissipates, its detection in essence traces energy on a galactic scale.

It has long been suspected that turbulent motions in the lower solar atmosphere are propagated outward as waves in some form, which ultimately shock the thin atmosphere above the surface (the photosphere).

The turbulent motion of superhot plasma causes the magnetic field coursing within to cycle between periods of low and high intensity — resulting in sunspots and solar flares.

Further study could help geologists understand the turbulent motion of the earth's liquid core, which generates the magnetic field and may initiate its flips.

«We used a technique called «lucky imaging», whereby individual sharp frames are extracted from short movies of Jupiter to «freeze» the turbulent motions of our own atmosphere, to create a stunning new image of Jupiter's cloud layers,» explained Dr Fletcher.

According to this theory, magnetic fields in galaxies arise from the turbulent motions of interstellar gases.

These winds flow through a galaxy, and push material out of it, but their turbulent motions are such that part of the material can be re-captured by the gravitational pull of the galaxy itself.

«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.»
