Centimeter Polarimetry of the R Coronae Australis Region
Minho Choi, Ken'ichi Tatematsu, Kenji Hamaguchi +1
Circularly polarized 3.5 cm continuum emission was detected toward three radio sources in the R CrA region using the Very Large Array. The Class I protostar IRS 5b persistently sho…
Resolving a Class I Protostar Binary System with Chandra
Kenji Hamaguchi, Minho Choi, Michael F. Corcoran +3
Using a sub-pixel event repositioning technique, we spatially resolved X-ray emission from the infrared double system IRS 5 in the R Corona Australis molecular cloud with ~0.8" sep…
Centimeter Imaging of the R Coronae Australis Region
Minho Choi, Kenji Hamaguchi, Jeong-Eun Lee +1
The R CrA region was observed in the 3.5 and 6.2 cm continuum with high angular resolutions (0.6--1.7 arcseconds) using the Very Large Array. Archival data sets were also analyzed…
Millimeter Imaging of HH 24 MMS: A Misaligned Protobinary System
Miju Kang, Minho Choi, Paul T. P. Ho +1
The HH 24 MMS protostellar system was observed in the 6.9 mm continuum with a high angular resolution (0.5"). HH 24 MMS was resolved into two sources. The separation between source…
Three-Dimensional Observations of H_2 Emission around Sgr A East - I. Structure in the Central 10 Parsecs of Our Galaxy
Sungho Lee, Soojong Pak, Minho Choi +6
We have obtained velocity-resolved spectra of the H_2 v=1-0 S(1) (lambda = 2.1218 micron) emission line at 2 arcsec angular resolution (or 0.08 pc spatial resolution) in four regio…
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…
