This chapter discusses some of the other ways mode frequencies can be used, and what additional information they can provide about a star. It first considers how specific combinations of mode frequencies can be used to determine stellar properties. In addition, the properties of a star, such as the acoustic depth of the convection-zone base, are determined by fitting models of the signatures left by acoustic glitches to the frequencies or the second differences. This chapter discusses how one can use signatures of acoustic glitches to infer properties of the star in question. Period spacings of red giants are also potentially very useful, and this chapter discusses how to make use of them.Less
