Discovery of a bipolar and highly variable mass outflow from the symbiotic binary StH<i>α</i>190
A highly and rapidly variable bipolar mass outflow from StHα 190 has been discovered, the first time in a yellow symbiotic star. Permitted emission lines are flanked by symmetrical jet features and multi-component P-Cyg profiles, with velocities up to 300 km s-1. Given the high orbital inclination of the binary, …
