SUBARU Near-Infrared Imaging Polarimetry of Misaligned Disks Around The SR24 Hierarchical Triple System
Satoshi Mayama, Sebastián Pérez, Nobuhiko Kusakabe +65
The SR24 multi-star system hosts both circumprimary and circumsecondary disks, which are strongly misaligned from each other. The circumsecondary disk is circumbinary in nature. In…
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…
A Recurrent Probabilistic Neural Network with Dimensionality Reduction Based on Time-series Discriminant Component Analysis
Hideaki Hayashi, Taro Shibanoki, Keisuke Shima +2
This paper proposes a probabilistic neural network developed on the basis of time-series discriminant component analysis (TSDCA) that can be used to classify high-dimensional time-…
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…
Vertical Structure and Kinematics of the Galactic Outer Disk
Nobuyuki Sakai, Takumi Nagayama, Hiroyuki Nakanishi +7
We report measurements of parallax and proper motion for four 22 GHz water maser sources as part of VERA Outer Rotation Curve project. All sources show Galactic latitudes of 2$…
Near-infrared Monitoring of the Accretion Outburst in the MYSO S255-NIRS3
Mizuho Uchiyama, Takuya Yamashita, Koichiro Sugiyama +10
We followed-up the massive young stellar object (MYSO) S255-NIRS3 (=S255-IRS1b) during its recent accretion outburst event in the Ks band with Kanata/HONIR for four years after its…
