JWST/MIRI Reveals the Evolution from Molecular to Atomic Disk Winds
Naman S. Bajaj, Ilaria Pascucci, Sylvie Cabrit +10
The evolution and dispersal of protoplanetary disks--governed by accretion, magnetically launched jets and winds, and photoevaporative winds--fundamentally shape planetary systems.…
Chemical Divergence and Water Depletion: Gas Properties of Evolved Upper Scorpius Disks Revealed by JWST/MIRI
Eshan Raul, Ke Zhang, Abygail Waggoner +25
Tracing the chemical evolution of protoplanetary disks over time requires observations of disks at different ages. However, most JWST/MIRI surveys published to date have targeted y…
Molecular Similarity and Water Diversity in Coeval Binary Disks: JWST/MIRI Observations of Sz 65 and Sz 66
Jinghuai Yao, Ke Zhang, Andrea Banzatti +10
We present JWST/MIRI Medium Resolution Spectrometer spectra of the wide-separation (projected separation au) binary protoplanetary disks Sz 65 (K7; ) and Sz…
Class I/II Jets with JWST: Mass loss rates, Asymmetries, and Binary induced Wigglings
Naman S. Bajaj, Ilaria Pascucci, Tracy L. Beck +11
We present JWST NIRSpec spectro-imaging observations of jets from four edge-on protoplanetary disks that exhibit clear signatures of MHD disk winds. Bipolar jets are detected and s…
JWST captures a sudden stellar outburst and inner disk wall destruction
Chengyan Xie, Ilaria Pascucci, Dingshan Deng +6
We present JWST/MIRI observations of T~Cha, a highly variable (3-5\,mag) accreting Sun-like star surrounded by a disk with a large (\,au) dust gap. We find that…
