asteroseismic

Asteroseismology, commonly referred to as asteroseismic, is the study of the internal structure and properties of stars by analyzing their oscillation modes. The term asteroseismology is derived from the Greek words "aster" meaning star and "sismos" meaning shaking or oscillation.

Asteroseismic studies involve observing the periodic changes in a star's brightness and spectrum, which result from its starquakes or internal oscillations. These oscillations are similar to those experienced on Earth during earthquakes, and they can reveal a star's internal structure, composition, and rotation rate. By analyzing the oscillation modes of stars, astronomers can infer properties such as mass, radius, age, and internal rotation rates.

Asteroseismology is typically applied to stars that are in various stages of their evolution, such as main-sequence stars, red giants, and oscillating giants. The field of asteroseismology has greatly benefited from the development of space-based telescopes and other observational technologies. The Kepler space telescope, launched in 2009, has made significant contributions to the field by obtaining detailed data on the oscillation modes of thousands of stars.

Asteroseismology has provided valuable insights into the internal structure and evolution of stars. By studying the internal workings of stars, astronomers can gain a better understanding of their origins, composition, and ultimate fate. The field has applications in various areas of astronomy, including the study of solar-like stars, the behavior of substellar objects, and the evolution of galaxy populations.
