JWST/MIRI coronagraphic search for planets in systems with gapped exoKuiper belts and proper motion anomalies
R. Bendahan-West, S. Marino, A. L. Carter +17
Over the past decade, ALMA has uncovered a range of substructures within exoKuiper belts, pointing to a population of undetected planets. With JWST's sensitivity, we now have the o…
JWST/NIRCam observations of HD~92945 debris disk: An asymmetric disk with a gap
C. Lazzoni, R. Bendahan-West, S. Marino +9
We present the first observations of the HD92945 debris disk obtained with JWST, targeting this nearby K0V star located at 21.54 pc from the Sun. High-contrast coronagraphic imagin…
Discovery of a Debris Disk Around TWA 20
Skyler Palatnick, Maxwell A. Millar-Blanchaer, Jingwen Zhang +20
We report the discovery of a debris disk surrounding the M3 star, TWA 20, revealed by JWST coronagraphic observations using the Near-infrared Camera (NIRCam). With reference-star d…
The Origins & Reservoirs of Exocomets
Michele Bannister, Susanne Pfalzner, Tim Pearce +11
Small bodies exist in distinct populations within their planetary systems. These reservoir populations hold a range of compositions, which to first order are dependent on formation…
Discovery of carbon monoxide emission from five debris disks around young A-type stars
A. Moór, P. Ãbrahám, à +7
Over the past fifteen years, surveys mainly at millimeter wavelengths have led to the discovery of 20 gas-bearing debris disks, most of them surrounding young intermediate-ma…
