A JWST, ALMA and VLA survey of the Ophiuchus-A star-forming region: Unveiling hidden dust mass and connecting infrared outflows to their radio origins
Isaac C. Radley, John D. Ilee, Gemma Busquet +18
We present an infrared, millimetre, and radio survey of 20 Class 0-III young stellar objects in the Ophiuchus A L1688 star-forming cluster, combining high-resolution (7-25 au) VLA…
EPISODE II: Variability in the CO and HO rovibrational absorption lines in a periodically variable protostar EC 53
Seokho Lee, Jeong-Eun Lee, Chul-Hwan Kim +19
We present two-epoch JWST NIRSpec and MIRI observations of the young protostar EC 53 (V371 Ser), a periodically variable source with well-characterized quiescent and burst phases.…
BISTRO Survey: Gravity-Dominated and Magnetically Regulated Star Formation in M17 SW
Mengke Zhao, Keping Qiu, Ji-hyun Kang +27
We present high-resolution magnetic field maps of the M17 SW molecular cloud using JCMT 850 m dust polarization at a scale of 14. The magnetic field exhibits a distinct arc-…
Radio Continuum and Water Maser Monitoring of the Outburst in HOPS 373: Free-Free Emission Does Not Respond to the Outburst
John Tobin, Doug Johnstone, Greg Herczeg +5
We present VLA C-band (5~cm) continuum, K-band (1.3~cm) continuum, and water maser (22.235 GHz) monitoring of the protostar HOPS-373. We additionally present the contemporaneous mo…
The long-term outburst(s) of GPSV16: from an intermediate to a FUor classification
Carlos Contreras Peña, Jeong-Eun Lee, Philip W. Lucas +8
FU Ori outbursts are thought to play a key role in stellar mass assembly and in the chemistry of protoplanetary disks during the early formation of stars. However, uncertainties re…
EPISODE IV: Ice Inventory in the Envelope of EC 53
Jaeyeong Kim, Jeong-Eun Lee, Chul-Hwan Kim +9
We present the 1.628 m spectra of the young protostar EC 53, obtained with JWST NIRSpec IFU and MIRI MRS during the quiescent and burst phases of its periodic brightness vari…
Direct evidence for magnetohydrodynamic disk winds driving rotating outflows in protostar HOPS 358
Chul-Hwan Kim, Jeong-Eun Lee, Doug Johnstone +4
Angular momentum removal is a fundamental requirement for star and planet formation, yet the mechanisms driving this process remain debated. Magnetohydrodynamic disk winds, launche…
EPISODE III: The Nested Jet/Outflow Morphology of EC 53 Revealed by JWST and ALMA
Seonjae Lee, Jeong-Eun Lee, Chul-Hwan Kim +8
We present an extensive study of the structure and kinematics of the jet and outflow of EC 53, a Class I protostar with a quasi-periodic variability, using combined James Webb Spac…
