The trigonometric parallax of IRAS 23385+6053 and physical properties of molecular clouds based on the VLBI astrometry
Shota Hamada, Mikito Kohno, Toshihiro Omodaka +5
We performed very long baseline interferometry (VLBI) observations to measure the trigonometric parallax of HO maser sources in the outer massive star-forming region IRAS 23385…
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…
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…
Outer Rotation Curve of the Galaxy with VERA III: Astrometry of IRAS 07427-2400 and Test of the Density-Wave Theory
Nobuyuki Sakai, Hiroyuki Nakanishi, Mitsuhiro Matsuo +6
We report the trigonometric parallax of IRAS 07427-2400 with VERA to be 0.185 0.027 mas, corresponding to a distance of 5.41 kpc. The result is consistent w…
VLBI Astrometry of AGB Variables with VERA -- A Mira Type Variable T Lepus
Akiharu Nakagawa, Toshihiro Omodaka, Toshihiro Handa +9
We conducted phase referencing VLBI observations of the Mira variable T~Lepus (T~Lep) using VERA, from 2003 to 2006. The distance to the source was determined from its annual paral…
Fundamental Parameters of the Milky Way Galaxy Based on VLBI astrometry
Mareki Honma, Takumi Nagayama, Kazuma Ando +31
We present analyses to determine the fundamental parameters of the Galaxy based on VLBI astrometry of 52 Galactic maser sources obtained with VERA, VLBA and EVN. We model the Galax…
