Abstract

(Abstract only) With the large number of surveys currently in operation there are many new potential variable stars discovered. These include programs such as TESS, KELT, ATLAS, ASAS-SN, and others. Each of these has a different cadence which might impact the classification assigned to each potential new variable star. Using our current group of robotic telescopes, we are able to obtain high cadence follow-up observations to check the published period and classification of these targets. The current group of telescopes consists of four telescopes on our campus observation deck: 0.13-m, 0.2-m, 0.25-m, and the 0.3-m. Recently we have added a 0.61-m PlaneWave CDK24 telescope to our campus dome which will provide high density data and data on fainter targets. This group allows us to follow-up on pulsating variables from about 4th to 14th magnitude. We will show a range of variables and a comparison of the periods from the original surveys with periods from our high-density light curves.
