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.…
Multiple Jets in the bursting protostar HOPS 373SW
Seokho Lee, Jeong-Eun Lee, Doug Johnstone +2
We present the outflows detected in HOPS 373SW, a protostar undergoing a modest brightness increase at 850 m. Atacama Large Millimeter/submillimeter Array (ALMA) observat…
Triple spiral arms of a triple protostar system imaged in molecular lines
Jeong-Eun Lee, Tomoaki Matsumoto, Hyun-Jeong Kim +9
Most stars form in multiple star systems. For a better understanding of their formation processes, it is important to resolve the individual protostellar components and the surroun…
TIMES II: Investigating the Relation Between Turbulence and Star-forming Environments in Molecular Clouds
Hyeong-Sik Yun, Jeong-Eun Lee, Neal J. Evans +14
We investigate the effect of star formation on turbulence in the Orion A and Ophiuchus clouds using principal component analysis (PCA). We measure the properties of turbulence by a…
TIMES I: a Systematic Observation in Multiple Molecular Lines Toward the Orion A and Ophiuchus Clouds
Hyeong-Sik Yun, Jeong-Eun Lee, Yunhee Choi +16
We have used the Taeduk Radio Astronomy Observatory to observe the Orion A and Ophiuchus clouds in the 10 lines of CO, CO, HCN, HCO, and NH and the…
Modeling Nitrogen Fractionation in the Protoplanetary Disk around TW Hya: Model Constraints on Grain Population and Carbon-to-Oxygen Elemental Abundance Ratio
Seokho Lee, Hideko Nomura, Kenji Furuya +1
Observations conducted using the Atacama Large Millimeter/submillimeter Array on the protoplanetary disk around TW Hya show the nitrogen fractionation of HCN molecules in HC…
IGRINS spectroscopy of Class I sources: IRAS 03445+3242 and IRAS 04239+2436
Seokho Lee, Jeong-Eun Lee, Sunkyung Park +4
We have detected molecular and atomic line emission from the hot and warm disks of two Class I sources, IRAS 03445+3242 and IRAS 04239+2436 using the high resolution Immersion GRat…
The warm CO gas along the UV-heated outflow cavity walls: a possible interpretation for the Herschel/PACS CO spectra of embedded YSOs
Seokho Lee, Jeong-Eun Lee, Edwin A. Bergin
A fraction of the mid- (= 14--13 to = 24--23) CO emission detected by the \textit{Herschel}/PACS observations of embedded young stellar objects (YSOs) has been attributed…
A PDR model for the FIR mid- CO ladder with universal rotational temperature in star forming region
Seokho Lee, Jeong-Eun Lee, Edwin A. Bergin +1
A photon dominated region (PDR) is one of the leading candidate mechanisms for the origin of the warm CO gas with near universal 300~K rotational temperature inferred from th…
L1448-MM observations by the Herschel Key program, "Dust, Ice, and Gas In Time" (DIGIT)
Jinhee Lee, Jeong-Eun Lee, Seokho Lee +7
We present Herschel/PACS observations of L1448-MM, a Class 0 protostar with a prominent outflow. Numerous emission lines are detected at 55 < lambda < 210 micrometer including CO,…
