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…

Do Water Fountain Jets Really Indicate the Onset of the Morphological Metamorphosis of Circumstellar Envelopes?

Bosco H. K. Yung, Jun-ichi Nakashima, Chih-Hao Hsia +1

The small-scale bipolar jets having short dynamical ages from "water fountain (WF)" sources are regarded as an indication of the onset of circumstellar envelope morphological metam…

Molecular jet emission and a spectroscopic survey of S235AB

R. A. Burns, T. Handa, T. Hirota +3

Context. The S235AB star forming region houses a massive young stellar object which has recently been reported to exhibit possible evidence of jet rotation - an illusive yet crucia…
