    Gravitational Waves and Stellar Evolution: What Waves Reveal About Star Life Cycles

    Introduction

    Gravitational waves, ripples in spacetime caused by the acceleration of massive objects, have opened a new frontier in astrophysics. By studying these waves, scientists can glean insights into stellar evolution, unraveling the lifecycle of stars from formation to their explosive ends as supernovae or black holes. This interdisciplinary approach illuminates the significance of gravitational waves in understanding how stars change over time and the fundamental processes that govern their existence.
