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…

Pilot VLBI Survey of SiO v=3 J=1--0 Maser Emission around Evolved Stars

Hiroshi Imai, Miyako Oyadomari, Sze Ning Chong +9

In this Letter, we report detections of SiO v=3 J=1--0 maser emission in very long baseline interferometric (VLBI) observations towards 4 out of 12 long-period variable stars: WX P…
