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…
ALMA detections of circumstellar disks in the giant Hii region M17. Probing the intermediate- to high-mass pre-main-sequence population
J. Poorta, M. Hogerheijde, A. de Koter +8
Our current understanding is that intermediate- to high-mass stars form in a way similar to low-mass stars, that is, through disk accretion. However, the physical conditions that p…
A New Look at Disk Winds and External Photoevaporation in the -Orionis Cluster
K. Maucó, C. F. Manara, A. Bayo +12
Disk winds play a crucial role in the evolution of protoplanetary disks. Typical conditions for star and planet formation are in regions with intermediate or strong UV radiation fi…
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…
JWST Detects Neon Line Variability in a Protoplanetary Disk
C. C. Espaillat, T. Thanathibodee, C. V. Pittman +6
We report the first detection of variability in the mid-infrared neon line emission of a protoplanetary disk by comparing a JWST MIRI MRS spectrum of SZ Cha taken in 2023 with a Sp…
Disk Evolution in the three Nearby Star-Forming Regions of Taurus, Chamaeleon, and Ophiuchus
E. Furlan, D. M. Watson, M. K. McClure +8
We analyze samples of Spitzer Infrared Spectrograph (IRS) spectra of T Tauri stars in the Ophiuchus, Taurus, and Chamaeleon I star-forming regions, whose median ages lie in the <1…
