JWST NIRCam Reveals the Largest Known M-dwarf Debris Disk Around TWA 10 and New Scattered-Light Observations of the TWA 25 Debris Disk
Katie A. Crotts, Aarynn L. Carter, Beth Biller +26
We present JWST NIRCam observations of two M-dwarf systems located in the TW Hydra association, TWA 10 and TWA 25. Both systems harbor detected debris disks in the F200W and F444W…
A Search for Wide-orbit Planets Around M-dwarfs using Deep MIRI 15-micron Images
Yihan Li, Yifan Zhou, Rachel Bowens-Rubin +7
Wide-orbit (10 AU) gas giant planets shape the architecture of planetary systems, yet their occurrence rate remains poorly constrained. JWST has obtained the deepest mid-infrare…
Multiplicity of young isolated planetary mass objects in Taurus and Upper Scorpius
H. Bouy, G. Duchêne, G. Strampelli +12
Free-floating planetary mass objects--worlds that roam interstellar space untethered to a parent star--challenge conventional notions of planetary formation and migration, but also…
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…
Follow-Up Exploration of the TWA 7 Planet-Disk System with JWST NIRCam
Katie A. Crotts, Aarynn L. Carter, Kellen Lawson +39
The young M-star TWA 7 hosts a bright and near face-on debris disk, which has been imaged from the optical to the submillimeter. The disk displays multiple complex substructures su…
