Distance to VY Canis Majoris with VERA
We report on astrometric observations of H$_2$O masers around the red supergiant VY Canis Majoris carried out with VLBI Exploration of Radio Astrometry (VERA). Based on astrometric monitoring for 13 months, we successfully measured a trigonometric parallax of 0.88$\pm$0.08mas, corresponding to a distance of 1.14$^{+0.11} _{-0.09}$kpc. This is the most …
