Spectroscopic view on the outburst activity of the symbiotic binary AG Draconis
Laurits Leedjärv, Rudolf Gális, Ladislav Hric +2
Variations of the emission lines in the spectrum of the yellow symbiotic star AG Dra have been studied for over 14 years (1997 - 2011), using more than 500 spectra obtained on the…
The hot and the cool otbursts in the symbiotic system AG Draconis
M. Cikała, M. Mikołajewski, J. Osiwała +3
In this papper we present the analyses of the six (1998, 1997, 2001, 2002, 2003 and 2005) last outbursts of AG Draconis on the basis of low resolution visual spectroscopy. A new me…
Spectroscopy of the symbiotic star CH Cygni from 1996 to 2007
Mari Burmeister, Laurits Leedjärv
We monitored a set of emission lines in the optical spectra of CH Cyg using the 1.5-m telescope at the Tartu Observatory, Estonia. Most of the spectra were registered in the H alph…
Evidence for bipolar jets from the optical spectra of the prototypical symbiotic star Z Andromedae
Mari Burmeister, Laurits Leedjarv
We have studied optical spectra of the symbiotic star Z And, obtained during its latest outburst started in April 2006, with the aim of finding changes in the spectrum yielding clu…
