Browsing: Astroseismology

Astroseismology is a branch of astronomy that studies the internal structures of stars by observing their oscillations and vibrations. Similar to how seismologists study earthquakes to learn about Earth’s interior, astroseismologists analyze the pulsations within stars. These oscillations are typically caused by sound waves bouncing around inside a star, and they can provide crucial information about a star’s properties, such as its size, age, composition, and internal processes. Techniques in astroseismology have been greatly enhanced by space missions like Kepler and TESS, which observe stars over long periods to detect these subtle changes in brightness caused by stellar pulsations. By examining these variations, scientists can infer details about stellar interiors that are otherwise inaccessible, offering insights into stellar evolution and the life cycles of stars. This field is particularly potent for studying stars similar to the Sun and red giants, enhancing our understanding of stellar physics and the dynamics of celestial bodies.
