The Sun

  • J.M. Vaquero
Part of the Astrophysics and Space Science Library book series (ASSL, volume 361)

Our Sun is an ordinary star of spectral type G2V. However, there are several reasons why its study deserves special attention. For example, it is the only star where we can directly observe details on its surface; this allows astronomers to test theories of great relevance. Let us mention only one of them: the identification of the process of nuclear fusion in its interior laid the foundation for discovering its age and for understanding the evolution of the stars. Another reason is that the Sun clearly influences the Earth’s environment at different time scales, producing events that have impressed both astronomers and laymen alike. The latter aspect is the one we will be addressing in this book.
