Abstract
We analyze the spectra of the quiet early-M dwarfs that the HADES project monitored for 3.5 years. The wavelength rangecovered by the spectra allows us to analyze simultaneously the CaII H&K doublet and the Hα line, while the intensive follow up gives us a large number of spectra (up to 100) for each targeted star. We show how the CaII H&K and Hα fluxesare correlated at low activity levels and we infer the evolution timescales of chromospheric active regions.
