Descripción
Helioseismology is able to study the solar interior through the
observation of the solar oscillation modes propagating inside the Sun.
Pressure-driven modes (p modes) provide a very detailed picture of the
external convective zone above 0.7 R[&sun;]and the radiative zone down
to ~0.2 R[&sun;] where only a few of such modes penetrate so far. To
study deeper layers, still containing more than 40% of the totals mass,
another type of oscillations are needed: the gravity-driven modes (g
modes). Since the early 19 80s, this type of mode has been looked for.
Only very recently have we have found some structures that are
compatible with some global properties of these modes in the GOLF/ SOHO
data. In this contribution we will show these signals. By explaining
them as the signature of the asymptotic properties of the ℓ = 1 g
modes, we could start constraining the solar core dynamics.
