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…
Refined classification of YSOs and AGB stars by IR magnitudes, colors, and time-domain analysis with machine learning
Hyunwook Jheonn, Jeong-Eun Lee, Jinho Lee +5
We introduce a binary classification model, {\it the Double Filter Model}, utilizing various machine learning and deep learning methods to classify Young Stellar Objects (YSOs) and…
Sub-Millimeter Variability in the Envelope & Warped Protostellar Disk of the Class 0 Protostar HOPS 358
Patrick D. Sheehan, Doug Johnstone, Carlos Contreras Peña +7
The JCMT Transient Survey recently discovered that the Class 0 protostar HOPS 358 decreased in 350 GHz continuum brightness by % over the course of four years before bright…
ALMA Spectral Survey of An eruptive Young star, V883 Ori (ASSAY): II. Freshly Sublimated Complex Organic Molecules (COMs) in the Keplerian Disk
Jae-Hong Jeong, Jeong-Eun Lee, Seonjae Lee +9
We present an investigation of Complex Organic Molecules (COMs) in the spatially resolved Keplerian disk around V883 Ori, an eruptive young star, based on a spectral survey carried…
