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.

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.

Even though the group did not detect any additional exoplanets in the 30 previous unobserved systems, the observations they made provided supplementary data that helped to characterize the abundance of planets in systems with debris disks.

Researchers looked at 130 single - star systems that the Spitzer Space Telescope had determined to have debris disks around them and compared them to 277 stellar systems that appeared not to have debris disks, making this the largest study to observe stars with debris disks.

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).

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.

The problem with this interpretation was that such collision events would create large debris disks which would glow brightly in the infrared, yet previous searches with NASA's Wide - field Infrared Survey Explorer, or WISE, had found no such excess infrared emission from KIC 8462852.

According to Akeson et al (2009), Denebola was first identified as having an circumstellar dust or «debris» disk from an excess of infrared radiation observed with the Infrared Astronomical Satellite (IRAS) in 1983 (Aumann and Probst, 1991, see G448.0, GL 448, or BS 4534).

About half of the new debris disks are close enough to the Sun that they are potential targets for imaging with coronagraphs to search for extrasolar planets that could be lurking within them.
