A Uniform Analysis of Debris Disks with the Gemini Planet Imager. I. An Empirical Search for Perturbations from Planetary Companions in Polarized Light Images [PDF]
The Astrophysical Journal, 2023 The Gemini Planet Imager (GPI) has excelled in imaging debris disks in the near-infrared. The GPI Exoplanet Survey imaged 24 debris disks in polarized H -band light, while other programs observed half of these disks in polarized J and/or K 1 bands. Using

Evidence for Misalignment between Debris Disks and Their Host Stars [PDF]
The Astrophysical Journal, 2023 We place lower limits on the obliquities between debris disks and their host stars for 31 systems by comparing their disk and stellar inclinations.

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

Impact of planetesimal eccentricities and material strength on the appearance of eccentric debris disks [PDF]
Astronomy & Astrophysics, 2018 Context. Since circumstellar dust in debris disks is short-lived, dust-replenishing requires the presence of a reservoir of planetesimals. These planetesimals in the parent belt of debris disks orbit their host star and continuously supply the disk with ...

Debris disks as signposts of terrestrial planet formation [PDF]
, 2011 We present models for the formation of terrestrial planets, and the collisional evolution of debris disks, in planetary systems that contain multiple unstable gas giants.

A Primordial Origin for the Gas-rich Debris Disks around Intermediate-mass Stars [PDF]
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: Structure, Composition, and Variability [PDF]
Annual Review of Astronomy and Astrophysics, 2018 Debris disks are tenuous, dust-dominated disks commonly observed around stars over a wide range of ages. Those around main sequence stars are analogous to the Solar System's Kuiper Belt and zodiacal light.

Radial Surface Density Profiles of Gas and Dust in the Debris Disk around 49 Ceti [PDF]
, 2017 We present ~0.4 resolution images of CO(3-2) and associated continuum emission from the gas-bearing debris disk around the nearby A star 49 Ceti, observed with the Atacama Large Millimeter/Submillimeter Array (ALMA).

Debris Disks in the Scorpius-Centaurus OB Association Resolved by ALMA [PDF]
, 2016 We present a CO(2-1) and 1240 um continuum survey of 23 debris disks with spectral types B9-G1, observed at an angular resolution of 0.5-1 arcsec with the Atacama Large Millimeter/Submillimeter Array (ALMA).

VARIATIONS ON DEBRIS DISKS. II. ICY PLANET FORMATION AS A FUNCTION OF THE BULK PROPERTIES AND INITIAL SIZES OF PLANETESIMALS [PDF]
, 2010 We describe comprehensive calculations of the formation of icy planets and debris disks at 30-150 AU around 1-3 solar mass stars. Disks composed of large, strong planetesimals produce more massive planets than disks composed of small, weak planetesimals.
