Long term trends in the 3.5 μ light curve of RX Puppis
Published online by Cambridge University Press: 12 April 2016
Extract
SAAO photometry of RX Pup at 3.5 μ between 1972 and 1981 shows a very well defined period of 580 days with an amplitude of 0.35 mag, which is attributed to a Mira variable component. The infrared variability of RX Pup was demonstrated by Feast, Robertson and Catchpole (1977), who also pointed out that the infrared colours were indicative of the presence of a Mira variable with a dust excess. Further evidence for the Mira comes from the observations of H2O in the infrared spectrum by Barton, Phillips and Allen (1979).
