Neutral atomic and molecular clouds and star formation in the outer Carina arm
Geumsook Park, Bon-Chul Koo, Kee-Tae Kim +1
We present a comprehensive investigation of HI (super)clouds, molecular clouds (MCs), and star formation in the Carina spiral arm of the outer Galaxy. Utilizing HI4PI and CfA CO su…
Near-Infrared Spectroscopy of Dense Ejecta Knots in the Outer Eastern Area of the Cassiopeia A Supernova Remnant
Bon-Chul Koo, Yong-Hyun Lee, Jae-Joon Lee +1
The Cassiopeia A supernova remnant has a complex structure, manifesting the multidimensional nature of core-collapse supernova explosions. To further understand this, we carried ou…
He abundance of Dense Circumstellar Clumps in the Cassiopeia A Supernova Remnant
Bon-Chul Koo, Dongkok Kim, Sung-Chul Yoon +1
We report on the result of He abundance analysis of dense circumstellar clumps in the young supernova remnant Cassiopeia A. These clumps, which are called quasi-stationary flocculi…
Ice features of low-luminosity protostars in near-infrared spectra of AKARI/IRC
Jaeyeong Kim, Jeong-Eun Lee, Woong-Seob Jeong +8
We present near-infrared spectra of three low-luminosity protostars and one background star in the Perseus molecular cloud, acquired using the Infrared Camera (IRC) onboard the \te…
Unusually high HCO+/CO ratios in and outside supernova remnant W49B
Ping Zhou, Gao-Yuan Zhang, Xin Zhou +10
Galactic supernova remnants (SNRs) and their environments provide the nearest laboratories to study SN feedback. We performed molecular observations toward SNR W49B, the most lumin…
Shocked Molecular Hydrogen and Broad CO lines from the Interacting Supernova Remnant HB 3
J. Rho, T. H. Jarrett, L. N. Tram +6
We present the detections of shocked molecular hydrogen (H2) gas in near- and mid-infrared and broad CO in millimeter from the mixed-morphology supernova remnant (SNR) HB~3 (G132.7…
