Solar gravity modes have been actively sought because they directly probe the solar core (below 0.2 solar radius), but they have not been conclusively detected in the Sun because of their small surface amplitudes. Using data from the Global Oscillation at Low Frequency instrument, we detected a periodic structure in agreement with the period separation predicted by the theory for gravity dipole modes. When studied in relation to simulations including the best physics of the Sun determined… 
Amplitudes of Solar Gravity Modes
Solar gravity modes are mainly trapped inside the radiative region and are then able to provide information on the properties of the central part of the Sun granulation. However, there is no
On the Characteristics of the Solar Gravity Mode Frequencies
Gravity modes are the best probes for studying the dynamics of the solar radiative zone, and especially the nuclear core. This paper shows how specific physical processes influence the theoretical
Solar structure models
The Sun is a unique object in stellar evolution due to our unprecedent insight on its internal processes. We will illustrate in this review how the transition between a static vision to a more
Can We Constrain Solar Interior Physics by Studying the Gravity-Mode Asymptotic Signature?
Gravity modes are the best probes to infer the properties of the solar radiative zone, which represents 98% of the Sun’s total mass. It is usually assumed that high-frequency g modes give information
New insights on the solar core
Since the detection of the asymptotic properties of the dipole gravity modes in the Sun, the quest to find individual gravity modes has continued. An extensive and deeper analysis of 14 years of
Sensitivity of helioseismic gravity modes to the dynamics of the solar core
Context. The dynamics of the solar core cannot be properly constrained through the analysis of acoustic oscillation modes. Gravity modes are necessary to understand the structure and dynamics of the
Stochastic excitation of nonradial modes II. Are solar asymptotic gravity modes detectable
Detection of solar gravity modes remains a major challenge to our understanding of the innerparts of the Sun. Their frequencies would enable the derivation of constraints on the core physical
Solar inertial modes: Observations, identification, and diagnostic promise
The oscillations of a slowly rotating star have long been classified into spheroidal and toroidal modes. The spheroidal modes include the well-known 5-min acoustic modes used in helioseismology. Here
The quest for the solar g modes
Solar gravity modes (or g modes)—oscillations of the solar interior on which buoyancy acts as the restoring force—have the potential to provide unprecedented inference on the structure and dynamics
DETECTING GRAVITY MODES IN THE SOLAR 8 B NEUTRINO FLUX
The detection of gravity modes produced in the solar radiative zone has been a challenge in modern astrophysics for more than 30 yr and their amplitude in the core is not yet determined. In this

Differential Rotation and Dynamics of the Solar Interior
TLDR
Frequency splittings derived from GONG observations confirm that the variation of rotation rate with latitude seen at the surface carries through much of the convection zone, at the base of which is an adjustment layer leading to latitudinally independent rotation at greater depths.
Seismology of the Sun
TLDR
The oscillation frequencies yield a helium abundance that is consistent with cosmology, but they reinforce the severity of the neutrino problem, which should soon provide an important standard by which to calibrate the theory of stellar evolution.
The Seismic Structure of the Sun
Global Oscillation Network Group data reveal that the internal structure of the sun can be well represented by a calibrated standard model. However, immediately beneath the convection zone and at the

The Current State of Solar Modeling
TLDR
Data from the GONG project and other helioseismic experiments reveal subtle errors in the models, such as an excess in sound speed just beneath the convection zone, which is plausible that the sound-speed differences reflect weak mixing in stellar interiors.
