Blazhko
Blazhko is a term referring to a type of modulation observed in pulsating stars. Pulsating stars, also known as variable stars, are stars that change in brightness over time. One of the most well-known types of pulsating stars is the RR Lyrae star.
In the 1900s, the Russian astronomer Sergey Blazhko discovered a peculiar behavior in some RR Lyrae stars.
This change in amplitude of the brightness variations is what is now known as Blazhko modulation. The
The Blazhko effect is still not fully understood, and it is the subject of ongoing research in
Studying the Blazhko effect can provide valuable insights into the internal workings of pulsating stars and
