Query: On Flare Driven Global Waves   We recently presented evidence of a strong correlation between the energy in
the high-frequency part of the acoustic spectrum of the Sun and the solar X-ray
flux Karoff & Kjeldsen (2008). The discovery indicates that flares drive global
oscillations in the Sun in the same way that the entire Earth is set ringing
for several weeks after a major earthquake, such as the 2004 December
Sumatra-Andaman one. If this indication turns out to be true we might be able
to use the relation between flares and the energy in the high-frequency part of
the acoustic spectrum to detect e.g. flares on the far side of the Sun and
flares on other solar-like stars. But, the discovery also opens many new
questions such as why is it only the high-frequency part of the acoustic
spectrum that is correlated with the X-ray flux? And, are there energy enough
in solar flares do drive global oscillations?
