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…
Water Snowline in Young Stellar Objects with Various Density Structures Using Radiative Transfer Models
Young-Jun Kim, Jeong-Eun Lee, Giseon Baek +1
Tracing the water snowline in low-mass young stellar objects (YSOs) is important because dust grain growth is promoted and the chemical composition varies at the water snowline, wh…
HCN and HNC in the Disk of an Outbursting Young Star, V883 Ori
Seonjae Lee, Jeong-Eun Lee, Seokho Lee
Hydrogen cyanide (HCN) and hydrogen isocyanide (HNC) are isomers with similar chemical properties. However, HNC can be converted into other molecules by reactions with atomic hydro…
ALMA Spectral Survey of An eruptive Young star, V883 Ori (ASSAY): I. What triggered the current episode of eruption?
Jeong-Eun Lee, Chul-Hwan Kim, Seokho Lee +7
An unbiased spectral survey of V883 Ori, an eruptive young star, was carried out with the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 6. The detected line emission…
Complex Organic Molecules in a Very Young Hot Corino, HOPS 373SW
Jeong-Eun Lee, Giseon Baek, Seokho Lee +6
We present the spectra of Complex Organic Molecules (COMs) detected in HOPS 373SW with the Atacama Large Millimeter/submillimeter Array (ALMA). HOPS 373SW, which is a component of…
Evidence of Accretion Burst: The Viscously Heated Inner Disk of the Embedded Protostar IRAS 16316-1540
Sung-Yong Yoon, Jeong-Eun Lee, Seokho Lee +5
Outbursts of young stellar objects occur when the mass accretion rate suddenly increases. However, such outbursts are difficult to detect for deeply embedded protostars due to thei…
The circumstellar environment around the embedded protostar EC 53
Seokho Lee, Jeong-Eun Lee, Yuri Aikawa +2
EC53 is an embedded protostar with quasi-periodic emission in the near-IR and sub-mm. We use ALMA high-resolution observations of continuum and molecular line emission to describe…
The ice composition in the disk around V883 Ori revealed by its stellar outburst
Jeong-Eun Lee, Seokho Lee, Giseon Baek +6
Complex organic molecules (COMs), which are the seeds of prebiotic material and precursors of amino acids and sugars, form in the icy mantles of circumstellar dust grains but canno…
Formation of Wide Binaries by Turbulent Fragmentation
Jeong-Eun Lee, Seokho Lee, Michael Dunham +4
Understanding the formation of wide binary systems of very low mass stars (M 0.1 Msun) is challenging. The most obvious route is via widely separated low-mass collapsing frag…
Simultaneous observation of water and class I methanol masers toward class II methanol maser sources
Hyunwoo Kang, Kee-Tae Kim, Do-Young Byun +2
We present a simultaneous single-dish survey of 22 GHz water maser and 44 GHz and 95 GHz class I methanol masers toward 77 6.7 GHz class II methanol maser sources, which were selec…
"Dust, Ice, and Gas In Time" (DIGIT) Herschel Observations of GSS30-IRS1 in Ophiuchus
Hyerin Je, Jeong-Eun Lee, Seokho Lee +2
As a part of the "Dust, Ice, and Gas In Time" (DIGIT) key program on Herschel, we observed GSS30-IRS1, a Class I protostar located in Ophiuchus (d = 120 pc), with Herschel/Photodet…
Herschel Key Program, "Dust, Ice, and Gas In Time" (DIGIT): the origin of molecular and atomic emission in low-mass protostars in Taurus
Jeong-Eun Lee, Jinhee Lee, Seokho Lee +2
Six low-mass embedded sources (L1489, L1551-IRS5, TMR1, TMC1-A, L1527, and TMC1) in Taurus have been observed with Herschel-PACS to cover the full spectrum from 50 to 210 m as p…
