Starquakes on Flare stars

Flare Stars has been a subject of extending research for many decades at the Stefanion Observatory.  Apart of the spectacular flaring phenomena, the results of the analysis of the one colour (B) observations of the Stefanion Observatory at any stage of their activity (quiescence, weak flares, strong flares),indicate that: (1) Transient high frequency oscillations occur during the flare event and during the quiet-star phase as well; (2) The Observed frequencies range between 0.0025Hz (period 6.6min) and 0.033Hz (period 30s) not rigorously bounded. It is interesting that transient oscillations appear also far apart from the observed flares, during the quiet state of the star, as a result of the general magnetic activity of the star. The power spectrum of these oscillations resembles that of the solar like oscillation spectra i.e the sunquake spectra. In particular the starquake spectra  resembles that of a red subgiant.
