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 ...

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.

Solar Interior Rotation and its Variation
Living Reviews in Solar Physics, 2009 This article surveys the development of observational understanding of the interior rotation of the Sun and its temporal variation over approximately forty years, starting with the 1960s attempts to determine the solar core rotation from oblateness and ...

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.

The solar tachocline: a self-consistent model of magnetic confinement [PDF]
, 2011 In this dissertation we consider the dynamics of the solar interior, with particular focus on angular momentum balance and magnetic field confinement within the tachocline. In Part I we review current knowledge of the Sun's rotation.

Orbital dynamics of "smart dust" devices with solar radiation pressure and drag [PDF]
, 2011 This paper investigates how perturbations due to asymmetric solar radiation pressure, in the presence of Earth shadow, and atmospheric drag can be balanced to obtain long-lived Earth centred orbits for swarms of micro-scale 'smart dust' devices, without ...

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.
