All stars twinkle because their light is refracted in different directions as the atmosphere churns. However, some stars truly vary in brightness due to their physical properties or immediate surroundings. Such variable stars are interesting for many reasons, not least because they can serve as giant, remote physics laboratories. We cannot approach or touch them, nor can we control their behavior in any way, but we can understand how they work—in particular, how and why their brightness changes—which can lead to a deeper understanding of the universe.
I will present on the variability of two different stars that I have observed so far—one of which showed unexpected results—and discuss my current findings and plans for further observations.
