====== SONG Science ======

A detailed understanding of stars underpins much of astrophysics. Stars are the most fundamental astrophysical objects, they are the basic constituents of galaxies, and, to a large extent, the overall properties of the universe are controlled by their evolution.  Stars are huge balls of gas, and turbulent motions within them generate sound waves that cause the majority of them to wobble and ring like bells. The measurement and analysis of these acoustic oscillations is the only way to peer into the interior of a star.  We propose to acquire and assemble a telescope and spectrograph instrument that will be part of a world-wide network dedicated to `listening' to stars 24 hours per day. Constant monitoring is the only way to directly observe the workings of their interiors.
