Misaligned Twin Molecular Outflows From Class-0 Proto-stellar Binary System VLA 1623A Unveiled by ALMA
Chihomi Hara, Ryohei Kawabe, Fumitaka Nakamura +9
We present the results of ALMA observations toward the low-mass Class-0 binary system, VLA 1623Aab in the Ophiuchus molecular cloud in CO, CO, and CO(2--1) lin…
Nobeyama 45-m Mapping Observations toward Orion A.I. Molecular Outflows
Yoshihiro Tanabe, Fumitaka Nakamura, Takashi Tsukagoshi +9
We conducted an exploration of 12CO molecular outflows in the Orion A giant molecular cloud to investigate outflow feedback using 12CO (J = 1-0) and 13CO (J = 1-0) data obtained by…
Nobeyama 45-m Mapping Observations toward Orion A. III. Multi-Line Observations toward an Outflow-shocked Region, OMC-2 FIR
Fumitaka Nakamura, Shuri Oyamada, Sachiko Okumura +13
We present the results of mapping observations toward an outflow-shocked region, OMC-2 FIR 4 using the Nobeyama 45-m telescope. We observed the area in CO (), C$^{18}…
Discovery of an au-scale excess in millimeter emission from the protoplanetary disk around TW Hya
Takashi Tsukagoshi, Takayuki Muto, Hideko Nomura +10
We report the detection of an excess in dust continuum emission at 233~GHz (1.3~mm in wavelength) in the protoplanetary disk around TW~Hya revealed through high-sensitivity observa…
The Flared Gas Structure of the Transitional Disk around Sz 91
Takashi Tsukagoshi, Munetake Momose, Yoshimi Kitamura +8
We report resolution observations of the dust continuum at band 7, and the CO(3--2) and HCO(4--3) line emissions toward the transitional disk around Sz 91 with Atacam…
Extremely Dense Cores associated with Chandra Sources in Ophiuchus A: Forming Brown Dwarfs Unveiled?
Ryohei Kawabe, Chihomi Hara, Fumitaka Nakamura +15
On the basis of various data such as ALMA, JVLA, Chandra, {\it Herschel}, and {\it Spitzer}, we confirmed that two protostellar candidates in Oph-A are bona fide protostars or prot…
