Studies of stars and stellar populations, and the discovery and characterization of exoplanets, are being revolutionized by new satellite and telescope observations of unprecedented quality and scope. Some of the most significant advances have been in the field of asteroseismology, the study of stars by observation of their oscillations. This book gives a comprehensive technical introduction to this discipline. It not only helps students and researchers learn about asteroseismology; it also serves as an essential instruction manual for those entering the field. The book presents readers with the foundational techniques used in the analysis and interpretation of asteroseismic data on cool stars that show solar-like oscillations. The techniques have been refined, and in some cases developed, to analyze asteroseismic data collected by the NASA Kepler mission. Topics range from the analysis of time-series observations to extract seismic data for stars to the use of those data to determine global and internal properties of the stars. Reading lists and problem sets are provided, and data necessary for the problem sets are available online.Less

This chapter covers the basics of stellar pulsations, which are the main preoccupation of asteroseismology. Stellar pulsations may be detected by observing the variations of a star's brightness as a function of time. Radial velocity observations are also used in certain cases, though most pulsating stars have been studied using brightness variations. The focus of this chapter (and the book as a whole) is on stars with solar-like pulsations—the small-amplitude oscillations that are continually excited (in a stochastic manner) and damped by turbulence in the outer convection zones of the stars. In addition to a brief history of the study of solar-type oscillations, this chapter also provides an introduction to the basic appearance and properties of the pulsation spectra of solar-like oscillators.Less
