Abstract: Since the detection of the asymptotic properties of the dipole gravity modesin the Sun, the quest to find the individual gravity modes has continued. Adeeper analysis of the GOLF-SoHO data unveils the presence of a pattern ofpeaks that could be interpreted as individual dipole gravity modes. Thecomputed collapsed spectrum -around these candidate modes- uncovers thepresence of a quasi constant frequency splitting, in contrast with regionswhere no g modes are expected in which the collapsogram gives random results.Besides, the same technique applied to VIRGO-SoHO unveils some common signalsbetween both power spectra. Thus, we can identify and characterize the modes,for example, with their central frequency and splittings. This would open thepath towards new investigations to better constrain the solar core.
