Detection of periodic signatures in the solar power spectrum. On the track of l= 1 gravity modes
RA García,
Abstract: In the present work we show robust indications of the existence of g modes in the
Sun using 10 years of GOLF data. The present analysis is based on the exploitation of the
collective properties of the predicted low-frequency (25 to 140 microHz) g modes: their 

During the 23rd cycle of solar activity, the value of GEC varied from 0.8 to 3.2× 1032 …
