Context. Thanks to the vast and exquisite set of observations that have been made available for the Sun, our star is by far an ideal target for testing stellar models with a unique precision. A recent issue under consideration in the field is related to the progress in the solar surface abundances derivation that has led to a decrease of the solar metallicity. While the former high-metallicity models were in fair agreement with other observational indicators from helioseismology and solar… 

Amplitudes of Solar Gravity Modes: A Review

Solar gravity modes are considered the Rosetta Stone for probing and subsequently deciphering the physical properties of the solar inner-most layers. Recent claims of positive detection therefore

Rotating Solar Models in Agreement with Helioseismic Results and Updated Neutrino Fluxes

Standard solar models (SSMs) constructed in accordance with old solar abundances are in reasonable agreement with seismically inferred results, but SSMs with new low-metal abundances disagree with

Solar Chemical Abundances Determined with a CO5BOLD 3D Model Atmosphere

In the last decade, the photospheric solar metallicity as determined from spectroscopy experienced a remarkable downward revision. Part of this effect can be attributed to an improvement of atomic

Much of our understanding of the internal structure of the Sun derives from so-called standard theoretical solar models. Unfortunately, none of those models agrees completely with observation. The


We evaluate the e†ect of electrostatic screening by ions and electrons on low-Z thermonuclear reac- tions in the Sun. We use a mean -eld formalism and calculate the electron density of the screening

The Relevance of Nuclear Reactions for Standard Solar Models Construction

The fundamental processes by which nuclear energy is generated in the Sun have been known for many years. However, continuous progress in areas such as neutrino experiments, stellar spectroscopy and

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

Experimental evidence of neutrinos produced in the CNO fusion cycle in the Sun.

This work provides experimental evidence of the primary mechanism for the stellar conversion of hydrogen into helium in the Universe, and paves the way towards a direct measurement of the solar metallicity using CNO neutrinos.

The 3D non-LTE solar nitrogen abundance from atomic lines

Nitrogen is an important element in various fields of stellar and Galactic astronomy, and the solar nitrogen abundance is crucial as a yardstick for comparing different objects in the cosmos. In

Solar structure and evolution

The Sun provides a critical benchmark for the general study of stellar structure and evolution. Also, knowledge about the internal properties of the Sun is important for the understanding of solar

Systematic Study of L-Shell Opacity at Stellar Interior Temperatures.

The first systematic study of opacity dependence on atomic number at stellar interior temperatures is used to evaluate discrepancies between measured and modeled iron opacity, and reveals shortcomings in models for density effects, excited states, and open L-shell configurations.
