Observing Cepheid Variables using the Robotic Telescopes on the BYU Observation Deck
Long period variable stars, such as Cepheids, require only one or two observations in a given night to establish a good light curve. Consequently, many such targets can be observed in one night. To reduce the overhead involved in manually centering a telescope on each individual object, we set up a robotic telescope system capable of automatically slewing to a target, taking images, and moving to the next target. Some Cepheid variables have been observed to undergo a period shift that is accompanied by a temperature change. By observing many such variables, we hope to find other instances of this occuring, to better understand the relationship between period and temperature.
