How does asteroseismology work?

Astroseismology is the study of the vibrations in a star. In simplest terms you take detailed measurements of the brightness or a spectral line(s) of a star (or both) over a (very) long period of time (months to years) and you look for a pattern in the variations of the data from the vibrations. Space observations are best because the atmosphere can cause irregularities that bury the pattern.


Could you give me an idea of the level of the answer?
Are you already familiar with spectra?
Do you know what photometry means?

Could you understand light curves or time series?
Do you know what Fourier analysis is?
Taking an average of data and subtracting it out to amplify the variations ?
