Abstract

Abstract We detail the discovery of the short-period variable star presently known as TYC 2168-132-1. We have examined four nights of photometric observations of this star secured in 2015 and find it to be a δ Scuti variable with a primary period of 0.0737523 days. The star is multiperiodic with three dominant frequencies at 13.556, 7.047, and 11.757 cycles/day. Evidence from light curve morphology supports the δ Scuti classification. We estimate intrinsic values for color and luminosity that place TYC 2168-132-1 within the lower part of the instability strip.
