First VLBI Imaging of SiO $v=0$, $J=1\to 0$ Masers in VY Canis Majoris

Hiroko Shinnaga, Miyako Oyadomari, Hiroshi Imai +8

We achieved the first VLBI detections of the ground vibrational state ($v=0$) ${}^{28}$SiO (hereafter, SiO) and ${}^{29}$SiO masers of the $J=1\to 0$ rotational transitions, to…
