Abstract

The spectral signature of collimated bipolar jets have been discovered on high resolution spectra of Hen 3-1341 during the 1999 outburst, the first ever recorded for this symbiotic star. The jets show up as emission components at [FORMULA] km s-1 on both sides of the main emission lines. They were not present in quiescence. As a general rule for the jets from stellar objects, also those in Hen 3-1341 come together with evidence of mass loss via wind (strong P-Cyg profiles).

Key words: stars: binaries: symbiotic – stars: individual: Hen 3-1341 – ISM: jets and outflows

* Based on observations collected with the telescopes of the Padova & Asiago Astronomical Observatories (Italy)
