ASAS-3 170634-5742.9 = NSV 8172 = CPD-57 8290 = GSC 08734-02066
The star is classified as a CEP: in the NSV catalogue with a G5 spectrum.
SIMBAD gives G5Iab: as the luminosity class.
This is similar to AI CMi and the lightcurve is AI CMi-like!
ASAS-3 data show it is not a cepheid.
At first instance I thought of an RCB type but it looks more like a
semiregular.
Maybe another protoplanetary object?
If so, this behaviour might be typical for this kind of stars.
Type= L:
V= 9.74 - 11.52
Regards,
Sebastian.
