Baker-Kippenhahn Mechanism | Vibepedia

The Baker-Kippenhahn mechanism is a fundamental astrophysical theory demonstrating that opacity-driven instability causes pulsations in Cepheid variable stars. Developed by Baker and Kippenhahn in 1962, this mechanism explains how changes in stellar opacity can trigger the rhythmic expansion and contraction observed in certain types of stars, revolutionizing our understanding of stellar dynamics.
