We compute a new generation of standard solar models (SSMs) that includes recent updates on some important nuclear reaction rates and a more consistent treatment of the equation of state. Models also include a novel and flexible treatment of opacity uncertainties based on opacity kernels, required in light of recent theoretical and experimental works on radiative opacity. Two large sets of SSMs, each based on a different canonical set of solar abundances with high and low metallicity (Z), are… 

The B16 Standard Solar Models

We describe a new generation of standard solar models (SSMs), Barcelona 2016 or B16 for short, that includes recent updates on some important nuclear reaction rates, a more consistent treatment of

An updated discussion of the solar abundance problem

We discuss the level of agreement of a new generation of standard solar models (SSMs), Barcelona 2016 or B16 for short, with helioseismic and solar neutrino data, confirming that models implementing

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

Standard solar models: Perspectives from updated solar neutrino fluxes and gravity-mode period spacing

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

The impact of composition choices on solar evolution: age, helio- and asteroseismology, and neutrinos

The Sun is the most studied and well-known star, and as such, solar fundamental parameters are often used to bridge gaps in the knowledge of other stars, when these are required for modelling.

The Updated BaSTI Stellar Evolution Models and Isochrones. I. Solar-scaled Calculations

We present an updated release of the BaSTI (a Bag of Stellar Tracks and Isochrones) stellar model and isochrone library for a solar-scaled heavy element distribution. The main input physics that have

Effects of a revised 7Be e−-capture rate on solar neutrino fluxes

Context. Electron-capture on 7Be is the main production channel for 7Li in several astrophysical environments. Theoretical evaluations have to account for not only the nuclear interaction, but also

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

Helioseismic and neutrino data-driven reconstruction of solar properties

In this work we use Bayesian inference to quantitatively reconstruct the solar properties most relevant to the solar composition problem using as inputs the information provided by helioseismic and

Improved Calibration of the Radii of Cool Stars Based on 3D Simulations of Convection: Implications for the Solar Model

Main-sequence, solar-like stars (M ≲ 1.5 M⊙) have outer convective envelopes that are sufficiently thick to affect significantly their overall structure. The radii of these stars, in particular, are

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

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.
