ON THE RELATIONSHIP BETWEEN DEBRIS DISKS AND PLANETS [PDF]

Astrophysical Journal, 2009
Dust in debris disks is generated by collisions among planetesimals. The existence of these planetesimals is a consequence of the planet formation process, but the relationship between debris disks and planets has not been clearly established. Here we analyze Spitzer/MIPS 24 and 70 micrometer data for 150 planet-bearing stars, and compare the incidence

A Constraint on the Amount of Hydrogen from the CO Chemistry in Debris Disks

The Astrophysical Journal, 2023
The faint CO gases in debris disks are easily dissolved into C by UV irradiation, while CO can be reformed via reactions with hydrogen. The abundance ratio of C/CO could thus be a probe of the amount of hydrogen in the debris disks.

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.

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.

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.
