ALMA Observations of the HD 110058 Debris Disk [PDF]
Astrophysical Journal, 2022 We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of the young, gas-rich debris disk around HD 110058 at 0.″3–0.″6 resolution. The disk is detected in the 0.85 and 1.3 mm continuum, as well as the J = 2–1 and J = 3–2 transitions

Multiwavelength Vertical Structure in the AU Mic Debris Disk: Characterizing the Collisional Cascade [PDF]
Astrophysical Journal, 2022 Debris disks are scaled-up analogs of the Kuiper Belt in which dust is generated by collisions between planetesimals. In the collisional cascade model of debris disks, the dust lost to radiation pressure and winds is constantly replenished by grinding ...

A Detailed Characterization of HR 8799's Debris Disk with ALMA in Band 7 [PDF]
Astronomical Journal, 2021 The exoplanetary system of HR 8799 is one of the rare systems in which multiple planets have been directly imaged. Its architecture is strikingly similar to that of the solar system, with the four imaged giant planets surrounding a warm dust belt ...

From Pebbles and Planetesimals to Planets and Dust: The Protoplanetary Disk–Debris Disk Connection [PDF]
Astrophysical Journal, 2021 The similar orbital distances and detection rates of debris disks and the prominent rings observed in protoplanetary disks suggest a potential connection between these structures. We explore this connection with new calculations that follow the evolution

Resolving Structure in the Debris Disk around HD 206893 with ALMA [PDF]
Astrophysical Journal, 2021 Debris disks are tenuous, dusty belts surrounding main-sequence stars generated by collisions between planetesimals. HD 206893 is one of only two stars known to host a directly imaged brown dwarf orbiting interior to its debris ring, in this case at a ...

A Deep Polarimetric Study of the Asymmetrical Debris Disk HD 106906 [PDF]
Astrophysical Journal, 2021 Located in the Lower Centaurus Crux group, HD 106906 is a young, binary stellar system. This system is unique among discovered systems in that it contains an asymmetrical debris disk, as well as an 11 M Jup planet companion, at a separation of ∼735 au ...

ALMA Images the Eccentric HD 53143 Debris Disk [PDF]
, 2022 We present ALMA 1.3 mm observations of the HD 53143 debris disk—the first infrared or millimeter image produced of this ∼1 Gyr old solar analog. Previous HST STIS coronagraphic imaging did not detect flux along the minor axis of the disk, which could ...

Extreme Variability of the V488 Persei Debris Disk [PDF]
Astrophysical Journal, 2021 V488 Persei is the most extreme debris disk known in terms of the fraction of the stellar luminosity it intercepts and reradiates. The infrared output of its disk is extremely variable, similar in this respect to the most variable disk known previously ...

A Layered Debris Disk around M Star TWA 7 in Scattered Light [PDF]
Astrophysical Journal, 2021 We have obtained Hubble Space Telescope (HST) coronagraphic observations of the circumstellar disk around M star TWA 7 using the Space Telescope Imaging Spectrograph (STIS) instrument in visible light.
