The Fe II emission lines in the optical spectrum of the symbiotic star RR Tel, observed by Crawford et al. (1999), have been analyzed applying the SAC method. We obtain information about the relative populations of the lower levels of the lines and,

Symbiotic novae are subclass of symbiotic stars - interacting binaries with wide orbits, whose photometric history is characterized by a single nova- like outburst lasting decades and caused by a thermonuclear runaway on the surface of a wind accreti

JHKL photometry of the symbiotic Mira RR Tel over 25 years shows variable fading in all bands which has been explained by obscuration due to dust as a result of the symbiotic nature of this binary. The evolutionary track (time changes) of the star ha

The aim of this work is to make available unpublished non-Fe+ emission line fluxes from optical spectra of the symbiotic nova RR Tel which were taken in 2000, and to compare them with fluxes of the same lines from spectra taken in 1996. After leaving

A study of the behaviour of the permitted Fe II and forbidden [FeII] emission lines during a dust obscuration episode, suggests a larger flux decrease for the permitted than for the forbidden lines. No other correlation with line properties have been

We continue our investigation of the emitting region of the symbiotic nova RR Telescopii by analyzing the emission line fluxes from high quality AAT optical spectra obtained in 2000 and by comparing these with previous observations. The fading found

We have examined the changes of line fluxes of RR Tel in the optical spectra taken in 2000 compared with the corresponding ones of the spectra taken in 1996. The fading of the lines leading to the apparent decrease of the radius of the line emitting
