Sentences with phrase «gas motion»

While recent observations have found such disks surrounding the baby - twin stars, named «circumbinary disks», those observations could not image the structures and gas motions of the disks to feed materials to the binary, because of the insufficient imaging resolution and sensitivity.
Astronomers have used the National Science Foundation's Very Long Baseline Array radio telescope to make the first - ever time - lapse movie showing details of gas motions around a star other than our Sun.
The inter-arm regions also exhibit a falling gas motion toward the central baby twin stars, namely, the ongoing feeding process of the materials to the baby twin stars.
Measuring gas motion by the Doppler Effect is one of the techniques in radio astronomy.
But not only the spatial distributions of titanium and iron resemble those in Cas A. Also the total amounts of these elements, their expansion velocities, and the velocity of the neutron star are in amazing agreement with those of Cas A. «This ability to reproduce basic properties of the observations impressively confirms that Cas A may be the remnant of a neutrino - driven supernova with its violent gas motions around the nascent neutron star,» concludes H. - Thomas Janka.
Scientists can measure temperature, pressure and gas motions when they study the signature of molecules in the signals they detect.
They observed L1551 NE in the emission from dust at a 0.9 - mm wavelength, a tracer of distribution of interstellar materials, and carbon monoxide molecular emission, which can be used to study gas motion with the Doppler Effect.
The research team also investigated the observed gas motion as seen in the carbon monoxide molecular emission, and identified faster rotating motions in the spiral arms and slower rotating motions in the inter-arm regions.
In fact, previous observations have found such collapsing gas motions to feed materials toward the central protostars.
Movie: Gas motion around the baby binary stars L1551 NE simulated with the supercomputer ATERUI.
These results show that the baby twin stars «shake» the surrounding circumbinary disk and induce the falling gas motion to feed the materials to the baby twin.
Intense surges in the gas motion are observed at two - thirds of the cores that have yet to form stars.
By analyzing the gas motion of an extraordinarily fast - moving cosmic cloud in a corner of the Milky Way, astronomers found hints of a wandering black hole hidden in the cloud.
The same effect is seen with the gas motions (caused by heat and rotation) inside a single star or gas cloud in our galaxy.
Gas motions to supply materials to the twin were also identified.
«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.»
«For example, we expect to be able to make movies of the gas motions around stars that are still in the process of forming and map the outflows that occur from dying stars, both at a level of detail that has never been possible before.»
