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.

Solar Oscillations and Convection. II. Excitation of Radial Oscillations [PDF]

The Astrophysical Journal, 2001
Solar p-mode oscillations are excited by the work of stochastic, non-adiabatic, pressure fluctuations on the compressive modes. We evaluate the expression for the radial mode excitation rate derived by Nordlund and Stein (Paper I) using numerical simulations of near surface solar convection.

3D numerical simulations of oscillations in solar prominences [PDF]

[eng] Context. Oscillations in solar prominences are a frequent phenomenon, and they have been the subject of many studies. A full understanding of the mechanisms that drive them and their attenuation has not been reached yet, however. Aims.

3D reconstruction of coronal loops by the principal component analysis [PDF]

, 2013
Knowing the three dimensional structure of plasma filaments in the uppermost part of the solar atmosphere, known as coronal loops, and especially their length, is an important parameter in the wave-based diagnostics of this part of the Sun.

Discovery of Energy‐Localized Trap States via Opto‐Electrical Spectroscopy in UWBG Perovskite La:SrSnO3 FETs

Advanced Functional Materials, EarlyView.
Combined UV–vis transmittance and wavelength‐dependent photo‐assisted DC I–V analyses reveal defect‐induced optical instability and a high density of deep donor‐like subgap traps in La‐doped SrSnO3. The resulting MOSFET achieves one of the highest on/off ratios reported for ABO3 perovskite devices, demonstrating the promise of stannate perovskites as ...

Evidence of 5 minute Oscillations from Parker Solar Probe

The Astrophysical Journal Letters
The Sun’s surface vibrates in characteristic 5 minute oscillations, known as p -modes, generated by sound waves trapped within the convection zone. Although these oscillations have long been hypothesized to reach into the solar wind, direct in situ ...

Solar-Like Oscillations in a Massive Star [PDF]

Science, 2009
Star Gazing Seismology of stars provides a unique insight into physical mechanisms taking place in their interior. Like the Sun, some stars have low-amplitude pulsations that are excited by turbulent convection in their outer layers. Belkacem et al. (p.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

A Neptunian mirror for solar oscillations [PDF]

Science, 2017
Asteroseismology![Figure][1] The Kepler satellite PHOTO: NASA AMES/JPL-CALTECH/T PYLE The Sun's brightness varies by a tiny amount because of seismic oscillations. The Kepler satellite has detected the same process on other Sun-like stars, which can be used to determine their mass ...
