英文摘要
We have studied the "water fountain" sources that exhibit bipolar fast jets traced by water vapor maser emission and associated with evolved star. We found a "helix" pattern of jet from one the water fountains and obtained its annual parallax distance. In another source, we found high velocity components of carbon-monoxide emission and an extremely low ^<12>CO/^<13>CO intensity ratio. These results suggest that the parental stars of the water fountains should be intermediate-mass (2-8 solar masses) stars and the jets should play a major role to shape planetary nebulae.
