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.

BINARIES AMONG DEBRIS DISK STARS [PDF]
The Astrophysical Journal, 2012 We have gathered a sample of 112 main-sequence stars with known debris disks. We collected published information and performed adaptive optics observations at Lick Observatory to determine if these debris disks are associated with binary or multiple stars.

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

A PRIMER ON UNIFYING DEBRIS DISK MORPHOLOGIES [PDF]
The Astrophysical Journal, 2016 ABSTRACT A “minimum model” for debris disks consists of a narrow ring of parent bodies, secularly forced by a single planet on a possibly eccentric orbit, colliding to produce dust grains that are perturbed by stellar radiation pressure.

THE FREQUENCY OF DEBRIS DISKS AT WHITE DWARFS [PDF]
The Astrophysical Journal, 2012 We present near- and mid-infrared photometry and spectroscopy from PAIRITEL, IRTF, and Spitzer of a metallicity-unbiased sample of 117 cool, hydrogen-atmosphere white dwarfs from the Palomar-Green survey and find five with excess radiation in the infrared, translating to a 4.3+2.7-1.2% frequency of debris disks.

Signposts of Multiple Planets in Debris Disks [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractWe review the nearby debris disk structures revealed by multi-wavelength images from Spitzer and Herschel, and complemented with detailed spectral energy distribution modeling. Similar to the definition of habitable zones around stars, debris disk structures should be identified and characterized in terms of dust temperatures rather than ...
