Implication of the period-magnitude relation for massive AGB stars and its astronomical applications
Akiharu Nakagawa, Tomoharu Kurayama, Hiroshi Sudou +1
We present astrometric very long baseline interferometry (VLBI) studies of AGB stars. To understand the properties and evolution of AGB stars, distances are an important parameter.…
Astrometric VLBI observations of HO masers in an extreme OH/IR star candidate NSV17351
Akiharu Nakagawa, Atsushi Morita, Nobuyuki Sakai +14
Results of astrometric very long baseline interferometry (VLBI) observations towards an extreme OH/IR star candidate NSV17351 are presented. We used the VERA (VLBI Exploration of R…
Annual parallax measurement of a Mira variable star BX Cam with VERA
Masako Matsuno, Akiharu Nakagawa, Atsushi Morita +8
We report results of astrometric VLBI observations toward a Mira variable star BX~Cam using the VLBI array "VERA". The observations were performed from February 2012 to November 20…
The First VERA Astrometry Catalog
VERA collaboration, Tomoya Hirota, Takumi Nagayama +59
We present the first astrometry catalog from the Japanese VLBI (very long baseline interferometer) project VERA (VLBI Exploration of Radio Astrometry). We have compiled all the ast…
Overall variation of the masers around W Hydrae in 28 years
Hiroshi Imai, Akiharu Nakagawa, Hiroshi Takaba
In this paper, we present the distribution of masers associated with the semi-regular variable star W Hydrae (W Hya). We have collected the radio interferometric data of the…
Outer rotation curve of the Galaxy with VERA IV: Astrometry of IRAS 01123+6430 and the possibility of cloud-cloud collision
Nagito Koide, Hiroyuki Nakanishi, Nobuyuki Sakai +13
As part our investigation into the Galactic rotation curve, we carried out Very Long Baseline Interferometry (VLBI) observations towards the star-forming region IRAS 01123+6430 usi…
