Abstract

We report the discovery of a new 13th magnitude variable star in Cassiopeia
close to the variable KP Cas.Analysis of six days of intensive photometry shows
a regular, near sinusoidal modulation with an amplitude of 0.024 mag and a
period of 0.43815(31)d.Although its colour indicates a spectral type around F0
the star probably suffers up to 2−2.5 magnitudes of extinction, so could be an Aor B-type star. Given the period, the low amplitude, the shape of the lightcurve
and the probable spectral type we consider it most likely to be a slowly pulsating
B-type (SPB) star.The variable has been registered in the International Variable
Star Index with the identifier VSX J003909.7+611233.
