Abstract
We present three new variable stars in the field around the star KELT-16, and new period estimates for four previously known contact binary systems in this field, ASASSN-V J205658.12+314215.9, ASASSN-V J205552.88+314615.9, ZTF J205733.78+314612.6, and ZTF J205627.42+315322.4. Due to the short periods of these three new variable stars, and the shape of the light curves, we believe they are contact binary systems. In addition, we have found that the star Gaia DR2 1864883699097368448 is an additional variable star candidate and possibly an eclipsing binary eclipse candidate star.
