Extreme Debris Disk Variability: Exploring the Diverse Outcomes of Large Asteroid Impacts During the Era of Terrestrial Planet Formation [PDF]

Astronomical Journal, 2019
The most dramatic phases of terrestrial planet formation are thought to be oligarchic and chaotic growth, on timescales of up to 100–200 Myr, when violent impacts occur between large planetesimals of sizes up to protoplanets.

On the forms of accretion of interstellar gas and dust during the formation of single stars and their planetary systems

Open Astronomy, 2021
In this paper, the mechanisms of star formation and the formation of the equatorial gas and dust disk of protostars are considered. The viscous dynamics of the interstellar matter of gas and dust disks is mainly determined by perturbations of the matter ...

Spatially resolved spectroscopy of the debris disk HD 32297 [PDF]

Astronomy & Astrophysics, 2019
Context. Spectro-photometry of debris disks in total intensity and polarimetry can provide new insight into the properties of the dust grains therein (size distribution and optical properties). Aims.

The REASONS Survey: Resolved Millimeter Observations of a Large Debris Disk around the Nearby F Star HD 170773 [PDF]

Astrophysical Journal, 2019
Debris disks are extrasolar analogs to our own Kuiper Belt and they are detected around at least 17% of nearby Sun-like stars. The morphology and dynamics of a disk encode information about its history, as well as that of any exoplanets within the system.

High-fidelity Imaging of the Inner AU Mic Debris Disk: Evidence of Differential Wind Sculpting? [PDF]

Astrophysical Journal, 2019
We present new high-fidelity optical coronagraphic imagery of the inner ∼50 au of AU Mic’s edge-on debris disk using the BAR5 occulter of the Hubble Space Telescope Imaging Spectrograph (HST/STIS) obtained on 2018 July 26–27.

RZ Piscium Hosts a Compact and Highly Perturbed Debris Disk

The Astrophysical Journal, 2023
RZ Piscium (RZ Psc) is well known in the variable star field because of its numerous irregular optical dips in the past 5 decades, but the nature of the system is heavily debated in the literature.
