When stars speak too fast: probing the first dredge up beyond the Nyquist frequency
Using asteroseismology, we analyse late subgiants and early red giants with long cadence data from Kepler. These two phases are key for studying the first dredge-up, when deep convection transports nuclear-processed material to the stellar surface. Asteroseismology constrains stellar masses and radii through the global seismic parameters νmax
