  skos:definition """The surface of the sun oscillates in certain modes defined by the
number¿of latitudinal and longitudinal modal planes. The sun vibrates
in¿multiple modes simultaneously, each mode typically having a
different¿amplitude. Observing the amplitudes of the various solar
oscillation¿modes is a way to look inside the sun. A commonly observed
phenomena is the¿"5-minute" oscillation, but other periods have been
observed from 10 to 160¿minutes on the long period scale to about 10
seconds on the short period¿scale. Also observed are so-called "g-mode"
oscillations (internal gravity¿waves) generated by turbulent convection
below the photosphere.¿These oscillations are the result of internal motions of
the sun and their study is known as helioseismology."""@en ;
