Helioseismology is one of the most successful fields of astrophysics. The observation and character-ization of solar oscillation has allowed solar seismologists to study the internal structure and
Helioseismic models of the sun with a low heavy element abundance
Helioseismology and neutrino experiments probing the internal structure of the Sun have yieldedmuch information, such as the adiabatic elasticity index, density, and sound speed in the convective and
Low heavy-element photospheric abundance: a challenge for solar modeling
Recent spectroscopic data pointing to low heavy-element abundances Z pose a severe problem for solar-structure modeling. The low-Z abundances imply a lower opacity and a relatively shallow convective
Progress in Global Helioseismology: A New Light on the Solar Modeling Problem and Its Implications for Solar-Like Stars
Since the first observations of solar oscillations, helioseismology has been one of the most successful fields of astrophysics. Data of high quality were obtained through the implementation of
Are recent solar heavy element abundances consistent with helioseismology
During the last decade the abundances of heavy elements in the Sun have been revised downwards leading to serious discrepancy between solar models constructed using these abundances and the available
The solar photospheric nitrogen abundance - Analysis of atomic transitions with 3D and 1D model atmospheres
Context. In recent years, the solar chemical abundances have been studied in considerable detail because of discrepant values of solar metallicity inferred from different indicators, i.e., on the one
Seismological challenges for stellar structure
Helioseismology has provided very detailed information about the solar interior, and extensive data on a large number of stars, although at less detail, are promised by the ongoing and upcoming
Seismic solar models from Ledoux discriminant inversions
Context. The Sun constitutes an excellent laboratory of fundamental physics. With the advent of helioseismology, we were able to probe its internal layers with unprecendented precision and
THE CHEMICAL COMPOSITION OF THE SUN FROM HELIOSEISMIC AND SOLAR NEUTRINO DATA
We perform a quantitative analysis of the solar composition problem by using a statistical approach that allows us to combine the information provided by helioseismic and solar neutrino data in an
Implications of solar wind measurements for solar models and composition
We critically examine recent claims of a high solar metallicity by von Steiger & Zurbuchen (2016, vSZ16) based on in situ measurements of the solar wind, rather than the standard spectroscopically

Helioseismological Implications of Recent Solar Abundance Determinations
We show that standard solar models are in good agreement with the helioseismologically determined sound speed and density as a function of solar radius, the depth of the convective zone, and the
New Solar Opacities, Abundances, Helioseismology, and Neutrino Fluxes
We construct solar models with the newly calculated radiative opacities from the Opacity Project (OP) and with recently determined (lower) heavy-element abundances. We compare the results from the
Solar Models Based on Helioseismology and the Solar Neutrino Problem
We have determined the sound-speed profile in the Sun by carrying out an asymptotic inversion of the helioseismic data from the Low-Degree (l) Oscillation Experiment (LOWL), the Global Oscillation
The Solar Heavy-Element Abundances. I. Constraints from Stellar Interiors
The latest solar atmosphere models including non-LTE corrections and three-dimensional hydrodynamic convection simulations predict a significant reduction in the solar metal abundance. This leads to
Constraining Solar Abundances Using Helioseismology
Recent analyses of solar photospheric abundances suggest that the oxygen abundance in the solar atmosphere needs to be revised downward. In this study, we investigate the consequence of this revision
Low abundances of heavy elements in the solar outer layers: comparisons of solar models with helioseismic inversions
Context: Recent solar photospheric abundance analyses have led to a significant reduction of the metal abundances compared to the previous determinations. (Z/X)S is 30% smaller, down to 0.0165. The
The ‘solar model problem’ solved by the abundance of neon in nearby stars
The interior structure of the Sun can be studied with great accuracy using observations of its oscillations, similar to seismology of the Earth. Precise agreement between helioseismological
Standard Solar Models in the Light of New Helioseismic Constraints. I. The Solar Core
In this paper, we examine a new, updated solar model that takes advantage of the recent reexamination of nuclear reaction rates and the microscopic diffusion of helium and heavy elements. Our best

The recent downward revision of solar photospheric abundances of oxygen and other heavy elements has resulted in serious discrepancies between solar models and solar structure as determined through
New Solar Models Including Helioseismological Constraints and Light-Element Depletion
We have computed new solar models using the same stellar evolution code as described in Charbonnel, Vauclair and Zahn (1992). This code, originating from Geneva, now includes the computation of
