Astrophysical properties and chromospheric activity of young stellar objects

In this talk I will address the problem of determining stellar parameters in young objects and measuring their magnetic activity level, which are strictly related. The photospheric/chromospheric activity produced by the stellar magnetic fields has indeed a strong impact, together with the mass accretion from circumstellar disks (when present), on the ...
