The Relevance of Nuclear Reactions for Standard Solar Models Construction
Frontiers in Astronomy and Space Sciences, 2021 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 helioseismic data and techniques requires ever more ...

Journal of High Energy Physics, 2022 We evaluate the statistical significance of the 3+1 sterile-neutrino hypothesis using ν e and ν ¯ $$ \overline{\nu} $$ e disappearance data from reactor, solar and gallium radioactive source experiments.

Implications of the Dark-LMA solution for neutrino mass matrices
Nuclear Physics B, 2021 In this work we have re-investigated two different kinds of texture zero ansatz of the low energy neutrino mass matrix in view of the Dark-Large-Mixing-Angle (DLMA) solution of the solar neutrino problem which can arise in the presence of non-standard ...

Neutrinos and Asteroseismology of Stars over the Helium Flash
The Astrophysical Journal, 2023 The helium flash, occurring in stars of 0.6–2.0 M _⊙ at the end of the red giant branch, is not observable via optical means due to the energy of the process being used to lift the core out of degeneracy.

Analysis of Solar Neutrino Data from Super-Kamiokande I and II
Entropy, 2014 We are going back to the roots of the original solar neutrino problem: the analysis of data from solar neutrino experiments. The application of standard deviation analysis (SDA) and diffusion entropy analysis (DEA) to the Super-Kamiokande I and II data ...

The Nature of Massive Neutrinos
Advances in High Energy Physics, 2013 The compelling experimental evidences for oscillations of solar, reactor, atmospheric, and accelerator neutrinos imply the existence of 3-neutrino mixing in the weak charged lepton current.

Sensitivity of a low threshold directional detector to CNO-cycle solar neutrinos
European Physical Journal C: Particles and Fields, 2018 A first measurement of neutrinos from the CNO fusion cycle in the Sun would allow a resolution to the current solar metallicity problem. Detection of these low-energy neutrinos requires a low-threshold detector, while discrimination from radioactive ...

The Astrophysical JournalThe ratio of metal abundance to hydrogen abundance of the solar photosphere, ( Z / X ) _s , has been revised several times. Standard solar models, based on these revised solar abundances, are in disagreement with seismically inferred results.

Refractive neutrino masses in the solar DM halo: can the dark-LMA solution be revived?
Journal of High Energy PhysicsNeutrinos can acquire “refractive masses” as a consequence of their interactions with ultralight dark matter (DM). We explore a model with two additional sterile neutrinos and an ultralight scalar field which acts as DM and interacts with all five ...
