Sentences with phrase «debris disks contain»

Debris disks contain the solid remnants of planet formation that are in collisional cascade, with particles ranging from kilometre - sized planetesimals down to micron - sized dust grains.

Not exact matches

Yet icy grains evaporate and collisions produce both gas and dust, so at some level all debris disks must contain some amount of gas.

Rieke notes that our solar system contains a faint debris disk of its own — micrometer - size dust particles slowly spiraling in toward the sun.

His calculations were the first to demonstrate that debris disks around the nearby stars Vega and β Pictoris are newly - formed planetary systems containing planets at least as large as Pluto and Mars.

In particular, I will focus on planets on eccentric orbits, not only because typical exoplanetary systems have been found to contain these, but also because their interactions with debris disks theoretically facilitates the transport of icy bodies within the habitable zone of planetary systems.

When researchers observed star systems containing debris disks with giant exoplanets in distant orbits, they noted that the star systems had similar dual dust disks analogous to the Solar System's two zones — the asteroid belt (between Mars and Jupiter) and the Kuiper Belt (beyond the orbit of Neptune).

Most galaxies in the observable universe contain a supermassive black hole at their center, one that is either active and surrounded by an accretion disk of dust, gas and other debris, or is dormant — lurking at the center, patiently awaiting its next meal.

This large debris disk is similar to the Kuiper Belt, which encircles the solar system and contains a range of icy bodies from dust grains to objects the size of dwarf planets, such as Pluto.
