TOMOGRAPHY OF THE SOLAR INTERIOR [PDF]
Modern Physics Letters A, 2006 Solar oscillations consist of a rich spectrum of internal acoustic waves and surface gravity waves, stochastically excited by turbulent convection. They have been monitored almost continuously over the last ten years with high-precision Doppler images of the solar surface.

Magneto-Rossby Waves and Seismology of Solar Interior
Frontiers in Astronomy and Space Sciences, 2018 Eleven-year Schwabe cycle in solar activity is not yet fully understood despite of its almost two century discovery. It is generally interpreted as owing to some sort of magnetic dynamo operating below or inside the convection zone.

SEISMIC CONSTRAINTS ON INTERIOR SOLAR CONVECTION [PDF]
The Astrophysical Journal, 2010 We constrain the velocity spectral distribution of global-scale solar convective cells at depth using techniques of local helioseismology. We calibrate the sensitivity of helioseismic waves to large-scale convective cells in the interior by analyzing simulations of waves propagating through a velocity snapshot of global solar convection via methods of ...

Possible Indications of Variations in the Directionality of Beta-Decay Products
Frontiers in Physics, 2021 Some experiments seem to yield strong evidence of variability of beta-decay rates, but other experiments may show little or no such evidence. Some recent experiments help clarify the situation.

Radial gradient of the solar rotation rate in the near-surface shear layer of the Sun
Frontiers in Astronomy and Space Sciences, 2022 We study the radial gradient of the solar rotation rate in the near-surface shear layer (NSSL) from about .950 R⊙ to the solar surface and its variation during Solar Cycles 23 and 24 with ring-diagram analysis applied to Global Oscillation Network Group (

Element diffusion in the solar interior [PDF]
The Astrophysical Journal, 1994 We study the diffusion of helium and other heavy elements in the solar interior by solving exactly the set of flow equations developed by Burgers for a multi-component fluid, including the residual heat-flow terms. No approximation is made concerning the relative concentrations and no restriction is placed on the number of elements considered.

The Astrophysical Journal, 2023 Previous studies analyzing the evanescent nature of acoustic waves in the lower solar atmosphere, up to 300 km above the photosphere, have shown an unexpected phase shift of an order of 1 s between different heights.

Solar Physics From Unconventional Viewpoints
Frontiers in Astronomy and Space Sciences, 2018 We explore new opportunities for solar physics that could be realized by future missions providing sustained observations from vantage points away from the Sun-Earth line.

Reducing interior temperature resulting from solar energy using three-dimensional surface patterns
Advances in Mechanical Engineering, 2015 Excessive solar energy can significantly increase interior temperatures and yield great energy demands for air conditioning. Whereas reducing energy consumptions is very crucial today, this article employs patterned glass technology which incorporates ...

Parameterization Studies of Solar Chimneys in the Tropics
Energies, 2013 The paper examines the effect of the solar chimney’s stack height, depth, width and inlet position on the interior performance (air temperature and speed at 1.20 m height above the ground) as well as proposes an optimal tropical solar chimney ...
