Parallax of a Mira variable R Ursae Majoris studied with astrometric VLBI
Akiharu Nakagawa, Tomoharu Kurayama, Makoto Matsui +5
We have measured an annual parallax of the Mira variable R~Ursae~Majoris (R~UMa) with the VLBI exploration for Radio Astronomy (VERA). From the monitoring VLBI observations spannin…
Annual Parallax Measurements of an Infrared Dark Cloud MSXDC G034.43+00.24 with VERA
Tomoharu Kurayama, Akiharu Nakagawa, Satoko Sawada-Satoh +5
We have measured the annual parallax of the H2O maser source associated with an infrared dark cloud MSXDC G034.43+00.24 from the observations with VERA (VLBI Exploration of Radio A…
New Distance and Revised Natures of High Mass Star Formation in G5.89-0.39
Kazuhito Motogi, Kazuo Sorai, Asao Habe +3
We report on the astrometric observations of the 22 GHz H2O masers in the high mass star-forming region G5.89-0.39 with VERA (VLBI Exploration of Radio Astrometry). Newly derived d…
