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.

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.

Primordial or Secondary? Testing Models of Debris Disk Gas with ALMA

The Astrophysical Journal, 2023
The origin and evolution of gas in debris disks are still not well understood. Secondary gas production from cometary material or a primordial origin have been proposed.

Planet forming disks, debris disks and the Solar System [PDF]

, 2020
VLT instruments and ALMA with their high spatial resolution have revolutionized in the past five years our view and understanding of how disks turn into planetary systems. This talk will briefly outline our current understanding of the physical processes

A Primordial Origin for the Gas-rich Debris Disks around Intermediate-mass Stars

The Astrophysical Journal Letters, 2023
While most debris disks consist of dust with little or no gas, a fraction have significant amounts of gas detected via emission lines of CO, ionized carbon, and/or atomic oxygen.

Debris disks around stars in the NIKA2 era [PDF]

EPJ Web of Conferences, 2020
The new NIKA2 camera at the IRAM 30m radiotelescope was used to observe three known debris disks in order to constrain the SED of their dust emission in the millimeter wavelength domain.

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.
