| 内容記述 | The symbiotic nova RR Telescopli has been observed with the 3.9m telescope of the Anglo-Australian Observatory (AAO), using the University College London Echelle Spectrograph in conjunction with a Tek CCD. It displays a rich emission line spectrum, ranging in excitation from N I to [Ni VIII]. We present a list of 824 measured lines, with their suggested identifications and absolute line intensities, covering a wavelength range from 3180 A to 9455 A. 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 2.3 m 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 ionization. |
