A method to extract p-modes frequencies from solar like stars acoustic spectra with S/N = 1/100
The necessity of finding a signal buried in noise is a common problem in astrophysics where noise limited observations are usually preceding interesting discoveries. In particular we are interested in the detection of p-mode oscillation frequencies of solar-like stars which, at least for the moment, have a very poor S/N ratio. In this work, it is
