[vsnet-chat 6613] V351 Ori (was Re: GT Ori variability type)

V351 Ori is an interesting star. Kovalchuk (1984, IBVS 2482)
observed a flare-like event during deep minimum. Van den
Ancker et al. (1996) observed that the star has ceased
Algol-like minima while has increased maximum brightness.
Some two years ago, V351 Ori was recognized as a delta Scuti
pulsator (I don't have exact reference at the hand).
Interestingly, fast periodic small-amplitude variations are
mentioned already in Kovalchuk's paper.
