Terrestrial planets, on the other h... ▽ More Debris disks are usually detected through the infrared excess over the photospheric level of their host star.

Not exact matches

The gravitational interactions created in the outer disk by this massive star apparently acted as a catalyst for the gathering of debris to form other smaller, more distant moons.

The resulting debris is absorbed into the disk of the more massive host galaxy before it approaches the center.

When material from this disk falls toward the black hole, the plunging debris gets so hot that it shines more brightly than the whole rest of its galaxy.

Study of collisional processes there will have impact on the interpretation of the much more distant (but numerous) main - sequence debris disks, about which much less is known.

For example, a large impact would create an enormous disk of debris, and while this would feed the creation of more massive moons, smaller bodies would likely be unable to coalesce.

The most favorable stars for disk detection are those with spectral types between A and K, while the statistics for debris disks detected around low - mass M - type stars is very low, either because they are rare or because they are more difficult to detect.

There has been no shortage of proposed explanations that have been put forth in order to account for the unusual observations, from the more mundane ones which include the presence of cometary fragments and large disk of debris from planetary collisions within the star system, to the more imaginative and fascinating ones which have invoked the presence of an extraterrestrial super-civilisation that is in the process of constructing gigantic megastructures around the star itself.

Disk Detective's goal was to locate protoplanetary disks — very early solar systems — around young stars, and debris disks around more mature ones.

Like Vega, it has a circumstellar dust or «debris» disk (more below).

So that means the white dwarf in this system probably came from a star slightly more massive than the A star that has the debris disk, maybe a B type star.

Since there's more material, the gas disk is usually hotter and more massive than the dusty debris disk.

This excess emission has been suggested to stem from debris di... ▽ More (abridged) Infrared excesses associated with debris disk host stars detected so far peak at wavelengths around ~ 100 -LCB- \ mu -RCB- m or shorter.

Once these planetary bodies acquire enough mass, they dramatically reshape the structure of their natal disk, fashioning rings and gaps as the planets sweep their orbits clear of debris and shepherd dust and gas into tighter and more confined zones.

Interferometric observations obtained with the VLTI and the KIN have identified near - and mid-infrared excesses attributed to ho... ▽ More [Abridged] Debris disks are extrasolar analogs to the solar system planetesimal belts.

The outer disk is revealed in reprocessed archival Hubble Space Telescope NICMOS F110W images, as well as new coronagraphic H band images from the Very Large Telescope SPHERE instr... ▽ More We present the first scattered - light images of the debris disk around 49 ceti, a ~ 40 Myr A1 main sequence star at 59 pc, famous for hosting two massive dust belts as well as large quantities of atomic and molecular gas.

The combination of our new data with the published 1.1 mi... ▽ More We present Hubble Space Telescope optical coronagraphic polarization imaging observations of the dusty debris disk HD 61005.
