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.

Solar Physics and Solar WindThis chapter introduces the reader to the solar interior, in particular the convection zone. The first section explores the solar cycle and the dynamo models that have been studied to explain this cycle. The second section explores helioseismology observations and analysis of the solar interior, and reviews the fundamental knowledge that has been ...

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.

Seismic Probes of Solar Interior Magnetic Structure [PDF]
Physical Review Letters, 2012 Sunspots are prominent manifestations of solar magnetoconvection and imaging their subsurface structure is an outstanding problem of wide physical importance. Travel times of seismic waves that propagate through these structures are typically used as inputs to inversions.

Confinement of the Solar Tachocline by Dynamo Action in the Radiative Interior [PDF]
Astrophysical Journal Letters, 2022 A major outstanding problem in solar physics is the confinement of the solar tachocline, the thin shear layer that separates nearly solid-body rotation in the radiative interior from strong differential rotation in the convection zone.

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 (

Screening potential and continuum lowering in a dense plasma under solar-interior conditions
Astronomy & Astrophysics, 2020 An accurate description of the screening potential induced by a hot, dense plasma is a fundamental problem in atomic physics and plasma physics, and it plays a pivotal role in the investigation of microscopic atomic processes and the determination of ...

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.

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 ...
