Scientific paper

We are conducting a small-scale short-period stellar variability survey using our 16-inch telescope at Baker Observatory. The goal is to search for previously undetected variability types and to increase membership of known pulsation classes. We are currently in the first portion of this survey which is to understand the sensitivity of our observations. Our strategy is to have four hour runs with short integrations and observe each field twice. We have begun collecting data with at least one known type of variable star in each field and are doing a blind study to recover the known variable and seek new variable stars. Our initial strategy for detecting variability is to use Fourier techniques for short-period (1 - 30 minutes) variability, phase-dispersion techniques for mid-period (0.5 to 4 hours) and a brightness comparator between the runs for long-period (4 hours to days) variations.
