Sentences with phrase «accreting disk»

In contrast to an actively accreting disk system, these passive disks have significantly lower near - infrared colors that are, in most cases, consistent with photospheric emission, suggesting the presence of an inner disk hole.

Bañados was looking in particular for quasars — some of the brightest objects in the universe, that consist of a supermassive black hole surrounded by swirling, accreting disks of matter.

The jets are thought to be produced by the ejection of material that is first pulled and acquired, or «accreted,» from one object to the other and swirled into a so - called accretion disk.

As mass is accreted into one of the disks it loses gravitational energy.

I apply numerical models to investigate the physical and chemical evolution of planetary materials, ranging from the small dust grains suspended in protoplanetary disks to the many kilometer - scale objects which accrete together to form planets.

We know that such objects need to have a low - density environment without other large galaxies nearby that would disturb it, but they also need a supply of small but gas - rich «dwarf» galaxies to accrete and build the really large diffuse extended disk.

In the first scenario, the Milky Way would have formed when star clusters merged to form the galaxy's bulge, or core, which then accreted more gas and dust to form its flattened disk of spiral arms.

The latest research shows that the relatively small OTS44 has a disk containing more than 10 times the mass of Earth, and that it is actively accreting material.

Further scrutiny of the TW Hya disk with GPI and SPHERE in their differential coronagraphic imaging modes may yield direct detection of the planet (s) that appears to be actively carving a gap in the TW Hya disk — especially if the putative planet is still actively accreting gas from the disk.

Under one popular theory (Boss, 1995), if such protoplanets become sufficiently massive while there is still abundant amounts of hydrogen and helium gases remaining in the disk, then they may accrete substantial amounts of those gases and become so - called gas giants (like Jupiter, Saturn, Uranus, and Neptune in the Solar System).
