Patterns in stars?!

Today I would like to share some graphs I have coded using something called Lomb Scargle. It's a mathematical algorithm that has helped me find different periods (time between deeper minima) for different RV Tau stars. So look out for the deep dips (minimas) in the graphs, because that is what's unique to these specific stars!

Each of the graphs above are considered RV Tau stars! Every light curve is different. All of them are not all perfectly shaped like the first light curve I posted. But just because they don't look the same, doesn't mean they aren't the same type of star. They each show deep minimas in various and really cool ways!
