RX J1615.3-3255 Archives

The 13.6 − 17.7 µm range of the GM Aur spectrum. The continuum-subtracted JWST-MIRI data (black, top panel) is overlaid with the total modeled emission (red, top panel) from molecules (bottom panel) H2O (blue) and OH (pink). Slab model fits were also performed for HCN, C2H2, 12CO2, 13CO2, and 13C 12CH2, however, H2O and OH were the only positive detections, while the remaining species did not match our detection criteria (see Section 3.1). The detected bright H I, H2, and atomic emission lines are labeled with dashed lines. -- astro-ph.SR

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.
