Abstract:

The symbiotic nova RR Telescopii has been observed with the 3.9m telescope at the Anglo-Australian Observatory (AAO), using the University College London Echelle Spectrograph (UCLES) in conjunction with a Tek CCD. It displays a rich emission line spectrum, ranging in excitation from NI to [NiVIII]. We present a list of 811 measured lines, with their suggested identifications and absolute line intensities, covering a wavelength range from 3180Å to 9455Å. The absolute line intensities have been derived by comparing the high resolution data with a flux-calibrated low resolution spectrum taken with the Australian National University 2.3m telescope. All of the lines have been successfully identified. Comparing our results with those of previous studies indicates that the RR Tel system is advancing towards higher degrees of ionisation.
