The Study of Debris Disks with SPICA [PDF]

SPICA joint European/Japanese Workshop, 2009
Debris disks are evidence that stars harbor reservoirs of dust-producing plantesimals on spatial scales similar the solar system. Debris disks present a wide range of sizes and structural features and there is growing evidence that, in some cases, they might be the result of the dynamical perturbations of a massive planet. Our solar system also harbors

Debris disks

EAS Publications Series, 2008
Debris disks are faint disks surrounding main-sequence stars. Their occurrence at ages beyond the typical dissipation time scales of YSO disks suggests that they are secondary in nature, being refurbished by the collisions of bodies of not-so-well known ...

Debris disks around M dwarfs: The Herschel DEBRIS survey [PDF]

Astronomy & Astrophysics
The Herschel open-time key program Disc Emission via a Bias-free Reconnaissance in the Infrared and Sub-millimeter (DEBRIS) is an unbiased survey of the nearest ∼100 stars for each stellar type A-M observed with a uniform photometric sensitivity to search for cold debris disks around them.

Secret of Longevity: Protoplanetary Disks as a Source of Gas in Debris Disks

The Astrophysical Journal
While protoplanetary disks (PPDs) are generally thought to disperse within several million years, recent observations have revealed gas in their older counterparts, debris disks.

The Disks In Scorpius–Centaurus Survey (DISCS). I. Four Newly Resolved Debris Disks in Polarized Intensity Light

The Astronomical Journal
The presence of infrared excesses around stars directly correlates with spatially resolved imaging detections of circumstellar disks at both millimeter and optical/near-infrared wavelengths.

Five new post-main-sequence debris disks with gaseous emission [PDF]

, 2020
Observations of debris disks, the products of the collisional evolution of rocky planetesimals, can be used to trace planetary activity across a wide range of stellar types.

THE COLLISIONAL EVOLUTION OF DEBRIS DISKS [PDF]

The Astrophysical Journal, 2013
We explore the collisional decay of disk mass and infrared emission in debris disks. With models, we show that the rate of the decay varies throughout the evolution of the disks, increasing its rate up to a certain point, which is followed by a leveling off to a slower value. The total disk mass falls off ~ t^-0.35 at its fastest point (where t is time)

THE STRUCTURE OF THE β LEONIS DEBRIS DISK [PDF]

The Astrophysical Journal, 2010
We combine nulling interferometry at 10 μm using the MMT and Keck Telescopes with spectroscopy, imaging, and photometry from 3 to 100 μm using Spitzer to study the debris disk around β Leo over a broad range of spatial scales, corresponding to radii of 0.1 to ~100 AU.
