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…
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…
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…
A Natural Laboratory for Astrochemistry, a Variable Protostar B335
Jeong-Eun Lee, Neal J. Evans, Giseon Baek +3
Emission lines from complex organic molecules in B335 were observed in four epochs, spanning a luminosity burst of about 10 years duration. The emission lines increased dramaticall…
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…
Spectral survey of a Hot core with an Eruptive Accretion in S255IR NIRS3 (SHEA): The discovery of class I and class II millimeter methanol maser transitions
Giseon Baek, Jeong-Eun Lee, Neal J. Evans +5
We report the detection of the millimeter CHOH masers including a new detection of class I (11-10A) and class II (6-5E) maser transitions towa…
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…
The JCMT Transient Survey: Four Year Summary of Monitoring the Submillimeter Variability of Protostars
Yong-Hee Lee, Doug Johnstone, Jeong-Eun Lee +49
We present the four-year survey results of monthly submillimeter monitoring of eight nearby (pc) star-forming regions by the JCMT Transient Survey. We apply the Lomb-Scargl…
Young Faithful: The Eruptions of EC 53 as It Cycles through Filling and Draining the Inner Disk
Yong-Hee Lee, Doug Johnstone, Jeong-Eun Lee +10
While young stellar objects sometimes undergo bursts of accretion, these bursts usually occur sporadically, making them challenging to study observationally and to explain theoreti…
The Relationship between Mid-Infrared and Sub-Millimetre Variability of Deeply Embedded Protostars
Carlos Contreras Peña, Doug Johnstone, Giseon Baek +5
We study the relationship between the mid-infrared and sub-mm variability of deeply embedded protostars using the multi-epoch data from the Wide Infrared Survey Explorer (/NE…
Radiative Transfer modeling of EC 53: An Episodically Accreting Class I Young Stellar Object
Giseon Baek, Benjamin A. MacFarlane, Jeong-Eun Lee +8
In the episodic accretion scenario, a large fraction of the protostellar mass accretes during repeated and large bursts of accretion. Since outbursts on protostars are typically id…
Observational signatures of outbursting protostars -- II: Exploring a wide range of eruptive protostars
Benjamin MacFarlane, Dimitris Stamatellos, Doug Johnstone +5
Young stars exhibit variability due to changes in the gas accretion rate onto them, an effect that should be quite significant in the early stages of their formation. As protostars…
Observational signatures of outbursting protostars - I: From hydrodynamic simulations to observations
Benjamin MacFarlane, Dimitris Stamatellos, Doug Johnstone +5
Accretion onto protostars may occur in sharp bursts. Accretion bursts during the embedded phase of young protostars are probably most intense, but can only be inferred indirectly t…
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…
Color Variability of HBC 722 in the Post-Outburst Phases
Giseon Baek, Soojong Pak, Joel D. Green +7
We carried out photometric observations for HBC 722 in SDSS r, i and z bands from 2011 April to 2013 May with a Camera for Quasars in Early uNiverse attached to the 2.1m Otto Struv…
