The B16 Standard Solar Models [PDF]
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 the equation of state and a novel and flexible treatment of opacity uncertainties.

Coupling 1D stellar evolution with 3D-hydrodynamical simulations on the fly – I. A new standard solar model [PDF]
Standard 1D stellar evolution models do not correctly reproduce the structure of the outermost layers of stars with convective envelopes. This has been a long-standing problem in stellar modelling affecting both the predicted evolutionary paths and the ...

Microwave Spectral Imaging of an Erupting Magnetic Flux Rope: Implications for the Standard Solar Flare Model in Three Dimensions [PDF]
We report microwave spectral imaging observations of an erupting magnetic flux rope during the early impulsive phase of the X8.2-class limb flare on 2017 September 10, obtained by the Expanded Owens Valley Solar Array.

Helioseismology and standard solar models [PDF]
We present a systematical analysis of uncertainties in the helioseismological determination of quantities characterizing the solar structure. We discuss the effect of errors on the measured frequencies, the residual solar model dependence and the uncertainties of the inversion method.

NEUTRINOS FROM A STANDARD SOLAR MODEL
A detailed estimate is presented of the possible uncertainty range for the neutrino flux from a standard solar model. Using present estimated errors in the key input parameters, detailed solar models are calculated to give an uncertainty in the theoretical ..nu../sub e/ capture rate in both the ongoing /sup 37/Cl experiment and the proposed experiment ...

Alive and well: A short review about standard solar models [PDF]
Standard solar models (SSMs) provide a reference framework across a number of research fields: solar and stellar models, solar neutrinos, particle physics the most conspicuous among them. The accuracy of the physical description of the global properties of the Sun that SSMs provide has been challenged in the last decade by a number of developments in ...

Status of the standard solar model prediction of solar neutrino fluxes [PDF]
The Standard Solar Model (BP04) predicts a total 8B neutrino flux that is 17.2% larger than measured in the salt phase of the SNO detector (and if it were significant it will indicate oscillation to sterile neutrinos). Hence it is important to examine in details uncertainties (and values) of inputs to the SSM.

Revisiting the standard solar model
The mutual consistency between standard solar models is studied based on the recent Los Alamos opacity tables. Satisfactory agreement is found among these models concerning the helium content and the neutrino capture rates. The reference model leads to a solar helium content of 0.276 + or - 0.012 by mass fraction. 75 references.

The nonadiabatic frequencies of a standard solar model and a solar model that includes helium diffusion are discussed. The nonadiabatic pulsation calculation includes physics that describes the losses and gains due to radiation.

Standard solar model uncertainties and their correlations in the analysis of the solar neutrino problem [PDF]
Abstract We present here an analysis of the theoretical uncertainties associated to the predicted solar neutrino rates for the current gallium, chlorine and water-Cerenkov experiments. We estimate the theoretical rates and their error matrices in three independent solar models (proposed by Bahcall and Pinsonneault, Turck-Chieze and Lopes, and Dar and
