Abstract

Since the detection of the asymptotic properties of the dipole gravity modes in the Sun, the quest to find the individual gravity modes has continued. A deeper analysis of the GOLF/SoHO data unveils the presence of a pattern of peaks that could be interpreted as dipole gravity modes. By collapsing the power spectrum we have obtained a quite constant splitting for those patterns in comparison to regions where no g-modes are expected. Besides, the same technique applied to VIRGO, unveils some common signals between both power spectra. Thus, we can identify and characterise the modes with their central frequency and splttings. This would open the path towards new investigations to better constrain the solar core.
