ALMA Detection of Extended Millimeter Halos in the HD 32297 and HD 61005 Debris Disks [PDF]
Astrophysical Journal, 2018 We present Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm (230 GHz) observations of the HD 32297 and HD 61005 debris disks, two of the most iconic debris disks because of their dramatic swept-back wings seen in scattered light images.

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.

Constraining the detectability of water ice in debris disks [PDF]
Astronomy & Astrophysics, 2019 Context. Water ice is important for the evolution and preservation of life. Identifying the distribution of water ice in debris disks is therefore of great interest in the field of astrobiology. Furthermore, icy dust grains are expected to play important

Search for Cold Debris Disks around M-dwarfs [PDF]
, 2006 Debris disks are believed to be related to planetesimals left over around stars after planet formation has ceased. The frequency of debris disks around M-dwarfs which account for 70% of the stars in the Galaxy is unknown while constrains have already ...

First Resolved Scattered-light Images of Four Debris Disks in Scorpius-Centaurus with the Gemini Planet Imager [PDF]
Astronomical Journal, 2019 We present the first spatially resolved scattered-light images of four debris disks around members of the Scorpius-Centaurus (Sco-Cen) OB association with high-contrast imaging and polarimetry using the Gemini Planet Imager (GPI).

Coplanar Circumbinary Debris Disks [PDF]
, 2012 We present resolved Herschel images of circumbinary debris disks in the alpha CrB (HD139006) and beta Tri (HD13161) systems. We find that both disks are consistent with being aligned with the binary orbital planes.

Modeling the Spatial Distribution and Origin of CO Gas in Debris Disks [PDF]
Astrophysical Journal, 2019 The detection of gas in debris disks raises the question of whether this gas is a remnant from the primordial protoplanetary phase, or released by the collision of secondary bodies.

Sculpting Eccentric Debris Disks with Eccentric Gas Rings [PDF]
Astrophysical Journal, 2019 Many debris disks seen in scattered light have shapes that imply their dust grains trace highly eccentric, apsidally aligned orbits. Apsidal alignment is surprising, especially for dust.

A peculiar class of debris disks from Herschel/DUNES - A steep fall off in the far infrared [PDF]
, 2012 Aims. We present photometric data of debris disks around HIP 103389 (HD 199260), HIP 107350 (HN Peg, HD206860), and HIP 114948 (HD 219482), obtained in the context of our Herschel Open Time Key Program DUNES (DUst around NEarby Stars). Methods.

Giant Impacts and Debris Disk Morphology
The Astrophysical Journal, 2023 Certain debris disks have nonaxisymmetric shapes in scattered light which are unexplained. The appearance of a disk depends on how its constituent Keplerian ellipses are arranged.
