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 scat…
MIRI MRS Observations of Beta Pictoris II. The Spectroscopic Case for a Recent Giant Collision
Christine H. Chen, Cicero X. Lu, Kadin Worthen +17
Modeling observations of the archetypal debris disk around Pic, obtained in 2023 January with the MIRI MRS on board JWST, reveals significant differences compared with that ob…
JWST-TST High Contrast: JWST/NIRCam observations of the young giant planet Pic b
Jens Kammerer, Kellen Lawson, Marshall D. Perrin +14
We present the first JWST/NIRCam observations of the directly-imaged gas giant exoplanet Pic b. Observations in six filters using NIRCam's round coronagraphic masks provide a…
