Currently, stellar activity is one of the limiting factors for the characterization of Earth-twins and for assessing their habitability: understanding the activity of M dwarfs is thus crucial. In this contribution I present the spectroscopic analysis of the quiet early-M dwarfs monitored within the HADES (HArps-n red Dwarf Exoplanet Survey) radial velocity survey. The spectra allow us to analyze simultaneously the Ca ii H&K doublet and the Hydrogen Balmer series, while the intensive follow up gives us a large number of spectra ( 100) for each target. We complement this dataset with ground-based follow-up photometry and archival X-ray data. I present our results on the activity-rotation-stellar parameters and flux-flux relationships, and discuss the correlation of emission fluxes at low activity levels and the evolution timescales of active regions.STAMPAenConference paper10.1017/S17439213190099312-s2.0-85092733698https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/analysis-of-the-chromosphere-and-corona-of-lowactivity-earlym-dwarfs/3AB913B612E555CE96EDCFAD11A8B2A0https://api.elsevier.com/content/abstract/scopus_id/850927336982020IAUS..354..355SFIS/05 - ASTRONOMIA E ASTROFISICA
