Recognizing Patterns in Debris Disks

, 2009
An extrasolar planet sculpts the famous debris dish around Fomalhaut; probably many other debris disks contain planets that we could locate if only we could better recognize their signatures in the dust that surrounds them. I will describe the latest 3-D

New debris disks in nearby young moving groups

, 2016
A significant fraction of nearby young moving group members harbor circumstellar debris dust disks. Due to their proximity and youth, these disks are attractive targets for studying the early evolution of debris dust and planetesimal belts.

The Role of Self-gravity in Debris-disk Warp Formation: The Case of HD 110058

The Astrophysical Journal Letters
We investigate the crucial role of self-gravity in the formation of warps in debris disks, focusing on the HD 110058 system as an example. Using advanced graphical-processing-unit-accelerated N -body simulations, we model the gravitational dynamics of a ...

Identifying and Characterizing Infrared Excesses in the Spitzer Kepler Survey (SpiKeS)

The Astrophysical Journal
We report our search for infrared excesses in the Spitzer/Infrared Array Camera survey of the Kepler field at 3.6 and 4.5 μ m. The Spitzer Kepler Survey contains ∼190,000 targets, which we reduce to ∼117,000 targets after applying multiple filters to ...

Implications for the formation of Oort cloud-like structures and interstellar comets in dense environments

Astronomy & Astrophysics
Most stars form in dense stellar environments, where frequent close encounters can strongly perturb and reshape the early architecture of planetary systems.

Modeling Debris Disk Evolution

, 2019
Understanding the formation, evolution, and architectures of planetary systems requires detailed knowledge of their components. Debris disks provide a means with which we can study them. The next decade will deliver a wealth of new information on the nearest systems. Parallel advances in modeling will be necessary to interpret these new datasets.

An Episode of Occultation Events in Gaia21bcv

The Astronomical Journal
A previously unremarkable star near the Canis Major OB1/R1 association underwent an episode of multiple deep brightness minima. Light curves based on archival Gaia, Zwicky Transient Facility (ZTF), and NEOWISE data and additional observations from the ...

Sharp Eccentric Rings in Planetless Hydrodynamical Models of Debris Disks

, 2013
Exoplanets are often associated with disks of dust and debris, analogs of the Kuiper Belt in our solar system. These "debris disks" show a variety of non-trivial structures attributed to planetary perturbations and utilized to constrain the properties of

Dusty debris disks: First light from exosolar planetary systems

, 2010
For stars with ages ≥ 10 Myr, circumstellar disks are dominated by a population of optically thin dust grains most likely associated with the erosion of a planetesimal population in a system that may have also formed planets. The key goal of this chapter

Microlensing Constraints on the Stellar and Planetary Mass Functions

The Astronomical Journal
The mass function (MF) of isolated objects measured by microlensing consists of both a stellar and a planetary component. We compare the microlensing MFs of A. Gould et al. and T. Sumi et al. to other measurements of the MF. The abundance of brown dwarfs
