Submillimeter continuum variability in Planck Galactic cold clumps
Geumsook Park, Kee-Tae Kim, Doug Johnstone +20
In the early stages of star formation, a protostar is deeply embedded in an optically thick envelope such that it is not directly observable. Variations in the protostellar accreti…
Precessing Jet and Large Dust Grains in the V380 Ori NE Star-forming Region
Minho Choi, Miju Kang, Jeong-Eun Lee +10
The V380 Ori NE bipolar outflow was imaged in the SiO and CO J = 1 - 0 lines, and dense cores in L1641 were observed in the 2.0-0.89 mm continuum. The highly collimated SiO jet sho…
Tracing the Spiral Structure of the Outer Milky Way with Dense Atomic Hydrogen Gas
Bon-Chul Koo, Geumsook Park, Woong-Tae Kim +3
We present a new face-on map of dense neutral atomic hydrogen (HI) gas in the outer Galaxy. Our map has been produced from the Leiden/Argentine/Bonn (LAB) HI 21-cm line all-sky sur…
Ammonia Imaging of the Disks in the NGC 1333 IRAS 4A Protobinary System
Minho Choi, Ken'ichi Tatematsu, Geumsook Park +1
The NGC 1333 IRAS 4A protobinary was observed in the ammonia (2, 2) and (3, 3) lines and in the 1.3 cm continuum with a high resolution (about 1.0 arcsec). The ammonia maps show tw…
Observations of Water Masers in the NGC 1333 IRAS 4 Region
Geumsook Park, Minho Choi
The NGC 1333 IRAS 4 region was observed in the 22 GHz H2O maser line with an angular resolution of about 0.08 arcseconds. Two groups of masers were detected, one near IRAS 4A and t…
