Wavelets: a powerful tool for studying rotation, activity, and pulsation in Kepler and CoRoT stellar light curves
Aims. The wavelet transform has been used as a powerful tool for treating several problems
in astrophysics. In this work, we show that the time–frequency analysis of stellar light curves …
