\subsection{Clump stars} stars}\label{clump}  After reaching the tip of the red giant branch, stars with $M\lesssim 2\mso$ ignite He in a degenerate core. This leads to a large release of energy, called the He-flash, which during a period of about 2 Myr lifts the degeneracy of the core leading to a stable He-burning phase.   Such transition phase might leave an asteroseismic signature, as suggested by \citet{2012ApJ...744L...6B}.
