Unraveling Stellar Magnetism: Quaking Giants Hold the Key

Red giants, massive stars in the later stages of their evolution, provide a unique opportunity for scientists to study the mysteries of stellar magnetism. By using starquakes, subtle oscillations at a star's surface, researchers can probe the magnetic fields deep within these giants. Recent observations have shown that the magnetic fields in the cores of red giants are more mysterious and stronger than expected. Understanding these magnetic fields is crucial for refining stellar models, calculating stellar ages more accurately, and determining the timelines of galaxy formation. This knowledge could also help in estimating the ages of potentially habitable exoplanets and answering questions about extraterrestrial life and galactic archaeology.
