Originally suggested to be related to η Carinae or R CrB stars (Pickering & Fleming, 1897; Payne-Gaposchkin & Gaposchkin, 1938), RX Pup was proposed by Swings & Struve (1941) to belong to the same category as Z And or T CrB. The star exhibits a red continuum with strong absorption features and several emission lines, including up to [Fe VII]. It is listed among confirmed stars with combination spectra in Bidelman (1954) and classified as a symbiotic star by Wackerling (1970) and Sanduleak & Stephenson (1973). In Swings & Klutz (1976), it was reported that high-excitation lines disappeared from the spectrum of RX Pup. Variable emission spectrum was confirmed by Klutz & Swings (1981), and a pulsation period of 580 days, attributed to Mira pulsation, was reported by Whitelock & Catchpole (1982). In Mikołajewska et al. (1999), detailed spectroscopic and photometric behavior of RX Pup was described, suggesting a possible SyRN classification due to evidence of an outburst around 1894 and in the 1970s, implying a period of around 80 years.
