Apocenter glow in eccentric debris disks: implications for Fomalhaut and epsilon Eridani [PDF]
, 2016 Debris disks often take the form of eccentric rings with azimuthal asymmetries in surface brightness. Such disks are often described as showing "pericenter glow", an enhancement of the disk brightness in regions nearest the central star.

Subtle and Spectacular: Diverse White Dwarf Debris Disks Revealed by JWST
The Astrophysical Journal LettersThis Letter reports 12 novel spectroscopic detections of warm circumstellar dust orbiting polluted white dwarfs using the JWST Mid-Infrared Instrument (MIRI). The disks span 2 orders of magnitude in fractional infrared brightness and more than double the

The vertical structure of debris disks and the impact of gas. [PDF]
Monthly notices of the Royal Astronomical Society, 2022 The vertical structure of debris disks provides clues about their dynamical evolution and the collision rate of the unseen planetesimals. Thanks to the ever-increasing angular resolution of contemporary instruments and facilities, we are beginning to ...

A New Sample of Warm Extreme Debris Disks from the ALLWISE Catalog [PDF]
Astrophysical Journal, 2021 Extreme debris disks (EDDs) are rare systems with peculiarly large amounts of warm dust that may stem from recent giant impacts between planetary embryos during the final phases of terrestrial planet growth.

Bridging the Gap between Protoplanetary and Debris Disks: Separate Evolution of Millimeter and Micrometer-sized Dust [PDF]
Astrophysical Journal, 2021 The connection between the nature of a protoplanetary disk and that of a debris disk is not well understood. Dust evolution, planet formation, and disk dissipation likely play a role in the processes involved.

Serendipitous Discovery of Nine White Dwarfs with Gaseous Debris Disks [PDF]
Astrophysical Journal, 2020 Optical spectroscopic observations of white dwarf stars selected from catalogs based on the Gaia DR2 database reveal nine new gaseous debris disks that orbit single white dwarf stars, about a factor of 2 increase over the previously known sample.
