Π PsA - Who Are You?
Abstract
Visual estimates are presented that show Pi PsA to have a semiregular light curve with an average amplitude of 0.7 magnitude and a period of approximately 8.625 days. These results are in contrast to the available literature, that either calls Pi PsA a small-amplitude Cepheid or states that the star was not variable in 1964 and 1970. Spectra and absolute magnitude indicate that the star lies outside the instability strip.
