Forecasting Catastrophe: Constraints on the Fomalhaut Main Belt Planetesimal Population from Observed Collisional Remnants
Arin M. Avsar, Kevin Wagner, Dániel Apai +2
Catastrophic planetesimal disruptions offer a unique opportunity to study and characterize large planetesimal populations in exoplanetary systems that are not currently detectable…
Theory of Exozodi Sources and Dust Evolution
Mark C. Wyatt, Tim D. Pearce, Nicole Pawellek +5
Exozodiacal dust disks (exozodis) are populations of warm (~300K) or hot (~1000K) dust, located in or interior to a star's habitable zone, detected around ~25% of main-sequence sta…
A Search for Collisions and Planet-Disk Interactions in the Beta Pictoris Disk with 26 Years of High Precision HST/STIS Imaging
Arin M. Avsar, Kevin Wagner, Dániel Apai +2
Beta Pictoris (Beta Pic)'s well-studied debris disk and two known giant planets, in combination with the stability of HST/STIS (and now also JWST), offers a unique opportunity to t…
Deepest limits on scattered light emission from the Epsilon Eridani inner debris disk with HST/STIS
Sai Krishanth P. M., Ewan S. Douglas, Ramya M. Anche +9
Epsilon Eridani ( Eri) is one of the first debris disk systems detected by the Infrared Astronomical Satellite (IRAS). However, the system has thus far eluded detection in scatt…
A Uniform Analysis of Debris Disks with the Gemini Planet Imager I: An Empirical Search for Perturbations from Planetary Companions in Polarized Light Images
Katie A. Crotts, Brenda C. Matthews, Gaspard Duchêne +37
The Gemini Planet Imager (GPI) has excelled in imaging debris disks in the near-infrared. The GPI Exoplanet Survey (GPIES) imaged twenty-four debris disks in polarized -band lig…
Exocometary gas in the HD 181327 debris ring
S. Marino, L. Matra, C. Stark +14
An increasing number of observations have shown that gaseous debris discs are not an exception. However, until now we only knew of cases around A stars. Here we present the first d…
