KIC 9715425 - Eruptive Variable Star

KIC 9715425 /APH22027710 is a spectral type A star, as listed at Planet Hunters, but may actually be a type B at 11199 (K). Tentatively tagged as a Gamma Doradus, it has eruptions through the quarters. First identified by Planet Hunters members one year ago.


This is what Talk member Kian Jek has to say about this star:

"This is an unusual one. There are no obvious APOs or contamination of any sort, so these spikes are a bit of a mystery. The pulsations continue right through these outbursts. In fact the pulsations resemble superhumps... could this yet be some strange species of dwarf nova? The double headed outburst at 340 appears to resemble the larger one at 600."
