Spatio-kinematical structure of the Galactic Nuclear Stellar Disk revealed in VLBI astrometry of circumstellar masers
Hiroshi Imai, Kohei Kurahara, Huib J. van Langevelde +2
SKA-VLBI astrometry will enable us to measure up to thousands of three dimensional motions of OH masers associated with circumstellar envelopes (CSEs) of OH/IR stars in the Nuclear…
Measuring Magnetic Fields from Water Masers in the Synchrotron Protostellar Jet in W3(HO)
C. Goddi, G. Surcis, L. Moscadelli +4
We report full polarimetric VLBA observations of water masers towards the Turner-Welch Object in the W3(OH) high-mass star forming complex. This object drives a synchrotron jet, wh…
Distance and proper motion measurement of water masers in Shapless 269 IRS 2w
Yoshiharu Asaki, Hiroshi Imai, Andrej Mikhailovich Sobolev +1
We present astrometric analysis of archival data of water masers in the star-forming region Sharpless 269 (S269) IRS 2w, observed with the VLBI Exploration of Radio Astrometry. An…
Distance and Proper Motion Measurement of the Red Supergiant, PZ Cas, in Very Long Baseline Interferometry H2O Maser Astrometry
Kozue Kusuno, Yoshiharu Asaki, Hiroshi Imai +1
We present the very long baseline interferometry H2O maser monitoring observations of the red supergiant, PZ Cas, at 12 epochs from 2006 April to 2008 May. We fitted maser motions…
