Formation History of HD 106906 and the Vertical Warping of Debris Disks by an External Inclined Companion

The Astrophysical Journal, 2023
HD 106906 is a planetary system that hosts a wide-orbit companion, as well as an eccentric and flat debris disk, which hold important constraints on its formation and subsequent evolution.

The far reaches of the β Pictoris debris disk [PDF]

, 2021
The nearby young star beta Pictoris hosts a rich and complex planetary system, with at least two giant planets and a nearly edge-on debris disk that contains several dynamical subpopulations of planetesimals.

The Apparent Absence of Forward Scattering in the HD 53143 Debris Disk

The Astrophysical Journal, 2023
HD 53143 is a mature Sun-like star and host to a broad disk of dusty debris, including a cold outer ring of planetesimals near 90 au. Unlike most other inclined debris disks imaged at visible wavelengths, the cold disk around HD 53143 appears as ...

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.

Debris Disk Results from the Gemini Planet Imager Exoplanet Survey's Polarimetric Imaging Campaign [PDF]

Astronomical Journal, 2020
We report the results of a ∼4 yr direct imaging survey of 104 stars to resolve and characterize circumstellar debris disks in scattered light as part of the Gemini Planet Imager (GPI) Exoplanet Survey. We targeted nearby (≲150 pc), young (≲500 Myr) stars

The Gemini Planet Imager View of the HD 32297 Debris Disk [PDF]

Astronomical Journal, 2020
We present new H-band scattered light images of the HD 32297 edge-on debris disk obtained with the Gemini Planet Imager. The disk is detected in total and polarized intensity down to a projected angular separation of 0.″15, or 20 au.

Long-term Evolution of Warps in Debris Disks—Application to the Gyr-old System HD 202628

The Astrophysical Journal, 2023
We present the results of N -body simulations meant to reproduce the long-term effects of mutually inclined exoplanets on debris disks, using the HD 202628 system as a proxy.

Formation of Gaps in Self-gravitating Debris Disks by Secular Resonance in a Single-planet System. II. Toward a Self-consistent Model

The Astrophysical Journal, 2023
High-resolution observations of several debris disks reveal structures such as gaps and spirals, suggestive of gravitational perturbations induced by underlying planets.

Multiband GPI Imaging of the HR 4796A Debris Disk [PDF]

Astrophysical Journal, 2020
We have obtained Gemini Planet Imager (GPI) J-, H-, K1-, and K2-Spec observations of the iconic debris ring around the young, main-sequence star HR 4796A. We applied several point-spread function (PSF) subtraction techniques to the observations (Mask-and-
