Quasivacuum solar neutrino oscillations [PDF]
Physical Review D, 2000 We discuss in detail solar neutrino oscillations with δm^2/E in the range [10^-10,10^-7] eV^2/MeV. In this range, which interpolates smoothly between the so-called ``just-so'' and ``Mikheyev-Smirnov-Wolfenstein'' oscillation regimes, neutrino flavor transitions are increasingly affected by matter effects as δm^2/E increases. As a consequence, the usual

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]
, 2012 We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

Assessment of DKIST/VTF capabilities for the detection of local acoustic source wavefronts
Frontiers in Astronomy and Space SciencesIntroductionRecent studies have demonstrated that temporal filtering can successfully identify local acoustic source wavefronts in radiative magnetohydrodynamic simulations of the solar photosphere.

The Role of High-frequency Transverse Oscillations in Coronal Heating
The Astrophysical Journal Letters, 2023 Transverse oscillations that do not show significant damping in solar coronal loops are found to be ubiquitous. Recently, the discovery of high-frequency transverse oscillations in small-scale loops has been accelerated by the Extreme Ultraviolet Imager ...

Diagnosis of the solar atmosphere using solar oscillations [PDF]
Symposium - International Astronomical Union, 1988 I present a review of the art of using acoustic and gravity waves as a tool to probe the structure of the solar atmosphere. The principle ideas behind the technique are discussed and a small bouquet of results is presented. The current discrepancies are pointed out, and in the last section a few thoughts are let loose about the inversion of data to ...

Modulation of gyrosynchrotron emission in solar and stellar flares by slow magnetoacoustic oscillations [PDF]
, 2006 Gyrosynchrotron emission generated by non-thermal electrons in solar and stellar coronal flares can be efficiently modulated by slow magnetoacoustic oscillations in the flaring loops.

The Astrophysical Journal, 2023 Much of the research on the magnetic activity of the Sun has been focused on its axisymmetric component. However, the longitudinal complexity plays a fundamental role in the solar magnetic activity.

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.

Seismological insights into solar and stellar magnetic activity cycles
EPJ Web of Conferences, 2017 The Sun’s magnetic activity cycle varies primarily on a time scale of approximately 11yrs from minimum to maximum and back again. It is well-known that the properties of the Sun’s acoustic oscillations are affected by the near-surface internal magnetic ...
