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…

Early Planet Formation in Embedded Disks (eDisk). XX. Constraining the Chemical Tracers of Young Protostellar Sources

Rajeeb Sharma, Jes K. Jørgensen, Merel L. R. van 't Hoff +12

Recent studies indicate that the formation of planets in protoplanetary disks begins early in the embedded Class 0/I phases of protostellar evolution. The physical and chemical mak…

ALMASOP. A Rotating Feature Rich in Complex Organic Molecules in a Protostellar Core

Shih-Ying Hsu, Chin-Fei Lee, Doug Johnstone +25

Interstellar complex organic molecules (COMs) in solar-like young stellar objects (YSOs), particularly within protostellar disks, are of significant interest due to their potential…

Determining the methanol deuteration in the disk around V883 Orionis with laboratory measured spectroscopy

Shaoshan Zeng, Jae-Hong Jeong, Takahiro Oyama +3

Deuterium fractionation, as studied through mono-deuterated methanol, is frequently used as a diagnostic tool to trace the physical conditions and chemical evolution of interstella…

Near- to mid-infrared spectroscopic study of ice analysis using the AKARI/IRC and Spitzer/IRS spectra

Jaeyeong Kim, Jeong-Eun Lee, Chul-Hwan Kim +2

We present the combined 2.530m spectra of four protostars acquired with the infrared camera and the infrared spectrograph on board the AKARI and Spitzer space telescopes, res…
