SOLAR NEUTRINO OSCILLATION – AN OVERVIEW [PDF]

PASCOS 2004, 2005
After a brief summary of the neutrino oscillation formalism and the solar neutrino sources and experiments I discuss the matter effect on solar neutrino oscillation. Then I discuss how the resulting alternative solutions are experimentally resolved in favour of the LMA solution, with particular exphasis on the SK, SNO and KL data.

The Importance of Berry Phase in Solar Acoustic Modes

The Astrophysical Journal Letters
An analytic expression for the frequencies of standing waves in stars, applicable to any radial order n , is derived from ray-tracing equations by the mean of Wigner–Weyl calculus.

Investigation of quasi-periodic varaiations in hard X-rays of solar flares

, 2009
The aim of the present paper is to use quasi-periodic oscillations in hard X-rays (HXRs) of solar flares as a diagnostic tool for investigation of impulsive electron acceleration.

Abnormal oscillation modes in a waning light bridge

, 2016
A sunspot acts as a waveguide in response to the dynamics of the solar interior; the trapped waves and oscillations could reveal its thermal and magnetic structures.

X-Ray and Spectral Ultraviolet Observations of Periodic Pulsations in a Solar Flare Fan/Looptop

The Astrophysical Journal
We present simultaneous X-ray and spectral ultraviolet observations of strikingly coherent oscillations in emission from a coronal looptop and fan structure, during the impulsive phase of a long-duration M-class solar flare.

An Investigation of Equivalence Principle Violations Using Solar Neutrino Oscillations in a Constant Gravitational Potential

, 1996
Neutrino oscillations induced by a flavor-dependent violation of the Einstein Equivalence Principle (VEP) have been recently considered as a suitable explanation of the solar electron-neutrino deficiency.
