The detection of dust gap-ring structure in the outer region of the CR Cha protoplanetary disk
Seongjoong Kim, Sanemichi Takahashi, Hideko Nomura +13
We observe the dust continuum at 225 GHz and CO isotopologue (12CO, 13CO, and C18O) J=2-1 emission lines toward the CR Cha protoplanetary disk using the Atacama Large Millimeter/Su…
Survey Observation of CHNH and Its Formation Process
Taiki Suzuki, Liton Majumdar, Kazuki Tokuda +6
We present the observational result of a glycine precursor, methylamine (CHNH), together with methanol (CHOH) and methanimine (CHNH) towards high-mass star-forming…
The First Detection of 13C17O in a Protoplanetary Disk: a Robust Tracer of Disk Gas Mass
Alice S. Booth, Catherine Walsh, John D. Ilee +4
Measurements of the gas mass are necessary to determine the planet formation potential of protoplanetary disks. Observations of rare CO isotopologues are typically used to determin…
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…
ALMA observations of layered structures due to CO selective dissociation in the Ophiuchi A plane-parallel PDR
M. Yamagishi, C. Hara, R. Kawabe +7
We analyze CO(=2-1), CO(=2-1), CO (=2-1), and 1.3 mm continuum maps of the Ophiuchi A photo-dissociation region (PDR) obtained with ALMA. Layered…
The Synthetic ALMA Multiband Analysis of the Dust Properties of the TW Hya Protoplanetary Disk
Seongjoong Kim, Hideko Nomura, Takashi Tsukagoshi +2
Analyzing multiband observations of dust continuum emission is one of the useful tools to constrain dust properties which help us to understand the physical properties of the disks…
Possibility of Concentration of Non-volatile Species near the Surface of Comet 67P/Churyumov-Gerasimenko
Taiki Suzuki, Yoshiharu Shinnaka, Liton Majumdar +4
The cometary materials are thought to be the reservoir of primitive materials in the Solar System. The recent detection of glycine and CHNH by the ROSINA mass spectrometer…
