A good example of finding a signal buried in noise, a common problem in Astrophysics,
is the search for stellar oscillations in the acoustic power spectrum of solar-like stars.
In this work it is shown that it is possible to find this type of signal
in the power spectrum of stellar oscillations if the peaks
are “almost” equally spaced in frequency, as the asymptotic theory for acoustic modes predicts.
This signature of the power spectra of the p-mode oscillations in solar-like stars is
used to design a method that allows the identification of the signal even when
this signal is completely buried in noise, .
Key words: methods: data analysis / stars: oscillations
