photometry, spectrographic observations, and AZ Canis minoris
Language:

Description:
Photometric and spectrographic observations of this δ Sct variable are presented in Fig. 1 of this paper. A comparison of photometric data over a period of 17 years indicates a binary nature of this variable. A tentative period of seven years has been derived. Applying relations applicable to this group of stars it has been shown that this variable is a giant star with a radius of about 2.6 Rθ pulsating in its first overtone.
