RR Lyrae stars are a type of pulsating variable star that are important distance indicators and tracers of stellar evolution in old stars. While they have very regular periods, many of them exhibit a modulation of their pulsation on a scale much longer than their pulsation periods, which is known as the Blazhko Effect. Understanding of this effect eluded astronomers for more than a century, but recent space-borne observations have shed light on a possible explanation. Not all of the aspects of the phenomenon are understood yet.
Our speaker: Terry decided to become an astronomer when he was eight years old. He obtained a bachelor’s degree in physics fro…
