Indications of Rapid Dust Formation in the Inner Region of a Protoplanetary Disk
Thanawuth Thanathibodee, Catherine Espaillat, Nuria Calvet +4
We report a significant increase in mid-infrared emission m in a transitional disk. The 2024 JWST/MIRI observation of the disk around CVSO 1942 reveals flux increase by…

JWST Reveals Carbon-rich Chemistry in a Transitional Disk
M. Volz, C. C. Espaillat, C. V. Pittman +6
We present JWST-MIRI Medium Resolution Spectrometer (MRS) observations of the Classical T Tauri stars GM Aur and RX J1615.3-3255 (J1615), both hosting transitional disks. Despite t…

Evidence for Dust Depletion in a Misaligned Protoplanetary Disk with JWST
C. C. Espaillat, T. Thanathibodee, Z. Zhu +12
Here we report the detection of dust depletion in a misaligned inner disk around UX Tau A using JWST MIRI spectra. Mid-infrared (MIR) continuum "seesaw" variability was detected in…
