JWST-MIRI's multi-dimensional view of mass loss in the irradiated disks of NGC 1977
Alice S. Booth, Qijia Zhou, Jinyoung Serena Kim +10
The evolution of protoplanetary disks, and consequently the outcomes of planet formation, are thought to be significantly altered in regions containing massive stars. Extreme cases…
The JDISC Survey: Inner Disk Chemistry of Class I/FS Disks and Tentative Evidence for Early Pebble Drift
Ke Zhang, Andrea Banzatti, Colette Salyk +22
We present the first chemical survey of Class I and Flat-Spectrum (I/FS) disks using JWST MIRI/MRS, targeting sixteen sources in the Ophiuchus star-forming region. Through empirica…
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.…
Extreme Debris Disks: Insights into Violent Collisions in Planet Formation and Destruction
Kate Y. L. Su, Attila Moor, Agnes Kospal +7
Debris disks are dusty structures around mature stars, primarily identified by infrared excesses in the stellar spectra. A subset, known as extreme debris disks (EDDs), exhibits st…
Nautilus Space Observatory: Unveiling the Diversity and Origin of Sub-Neptunes with the Nautilus Space Observatory
Luis Welbanks, Kylie E. Hall, Julien de Wit +10
Sub-Neptunes are the most common class of planets in the Galaxy, yet they have no Solar System analog and remain poorly understood as a population. JWST observations have revealed…
From Young to Older Disks: JWST/MIRI Evidence for Fading Molecular Emission and Hints for Elevated C/O in Upper Scorpius
Chengyan Xie, Ilaria Pascucci, Feng Long +23
We present JWST/MIRI spectroscopy of 14 disks in the older (~5-10 Myr) Upper Scorpius (USco) association and use slab of gas in local thermal equilibrium to infer basic gas propert…
