Debris disks are tenuous, dust-dominated disks commonly observed around stars over a
wide range of ages. Those around main sequence stars are analogous to the Solar System's …

Circumstellar dust exists around several hundred main sequence stars. For the youngest
stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be …

This paper uses observations of dusty debris discs, including a growing number of gas
detections in these systems, to test our understanding of the origin and evolution of this …

Debris belts on the periphery of planetary systems, encompassing the region occupied by
planetary orbits, are massive analogues of the Solar system's Kuiper belt. They are detected …

Debris disks are optically thin, almost gas-free dusty disks observed around a significant
fraction of main-sequence stars older than about 10 Myr. Since the circumstellar dust is short …

We describe calculations for the formation of icy planets and debris disks at 30-150 AU
around 1-3 M⊙ stars. Debris disk formation coincides with the formation of planetary …

Context. Observations of debris disks have significantly improved over the past decades,
both in terms of sensitivity and spatial resolution. At near-infrared wavelengths, new …

We report detection of cool dust surrounding solar-type stars from observations performed
as part of the Spitzer Legacy Science Program FEPS. From a sample of 328 stars having …

The majority of debris discs discovered so far have only been detected through infrared
excess emission above stellar photospheres. While disc properties can be inferred from …

IR surveys indicate that the dust content in debris disks gradually declines with stellar age.
We simulated the long-term collisional depletion of debris disks around solar-type (G2 V) …
