Solar neutrino physics oscillations: Sensitivity to the electronic density in the Sun's core

Understand

Solar neutrinos coming from different nuclear reactions are now detected with a high statistics.

• Consequently, an accurate spectroscopic analysis of the neutrino fluxes arriving on the Earth's detectors become available, in the context of neutrino oscillations.
• In this work, we explore the possibility of using this information to infer the radial profile of the electronic density in the solar core.
• So, we discuss the constraints on the Sun's density and chemical composition that can be determined from solar neutrino observations.
