Sentences with phrase «planetary debris disks»

The MIPS instrument team has documented the incidence, properties, and evolution of planetary debris disks around nearby stars.

Not exact matches

These «debris disks» are constantly fed by collisions among rocky bodies — the larger of which can survive and grow by continued accretion — because the tiny dust grains quickly fall onto the central star or get blown out of the planetary system.

«Over the past decade, we have learned that remnants of planetary systems around white dwarfs are ubiquitous, and over thirty debris disks have been found by now.

This finding is counterintuitive because higher - mass stars flood their planetary systems with energetic ultraviolet radiation that should destroy the carbon monoxide gas lingering in their debris disks.

The astronomers narrowed their search to stars between five and ten million years old — old enough to host full - fledged planetary systems and debris disks — and used ALMA to examine the millimeter - wavelength «glow» from the carbon monoxide in the stars» debris disks.

The discovery that the debris disks around some larger stars retain carbon monoxide longer than their Sun - like counterparts may provide insights into the role this gas plays in the development of planetary systems.

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.

Comparisons of the Kuiper belt with the debris disks around other stars provide important indications about both the Kuiper belt itself and the planetary environment around other stars.

My research is in celestial mechanics, including the architecture of extra-solar planetary systems, debris disks around stars, the Kuiper belt and asteroid belt, orbital resonances, and meteoritic bombardment on planets in the solar system.

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.

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.

Kuchner has also led a citizen science project called Disk Detective that allows users to scan WISE images for debris disks that could provide clues to planetary formation.

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.
