What is \textbf{"Asteroseismology"}?\\
Asteroseismology is  the science that studies the internal structure of stars by the interpretation of their pulsations. In fact certain stars pulsate and can effectively be considered huge musical instruments: depending on their size and internal structure they can oscillate at different frequencies, somewhat similar to spherical drums of different size, shape and material. The waves that propagate through the star can bring to surface precious information about the internal regions they crossed. This is similar to what seismologists do with our planet: they study at the surface waves excited by earthquakes to retrieve information about the structure and properties of the Earth's inner regions they crossed.% All without the need of digging a ~thousand miles deep hole in the ground.
