Photospheric high-frequency acoustic power excess in sunspot umbra: signature of magneto-acoustic modes [PDF]
, 2013 We present observational evidence for the presence of MHD (magnetohydrodynamic) waves in the solar photosphere deduced from SOHO/MDI (Solar and Heliospheric Observatory/Michelson Doppler Imager) Dopplergram velocity observations.

A Statistical Study of Short-period Decayless Oscillations of Coronal Loops in an Active Region
The Astrophysical Journal, 2023 Coronal loop oscillations are common phenomena in the solar corona, which are often classified as decaying and decayless oscillations. Using the high-resolution observation measured by the Extreme Ultraviolet Imager (EUI) on board the Solar Orbiter, we ...

Standing oscillations in a resonant sunspot atmosphere captured by integral field spectroscopy
Frontiers in Astronomy and Space SciencesThe solar atmosphere is replete with magnetohydrodynamic wave activity, with magnetic structures such as sunspots and pores able to channel wave energy flux efficiently into the outer atmosphere. Steep density and temperature gradients at the base of the

Solar neutrino oscillation phenomenology [PDF]
Pramana, 2004 This article summarises the status of the solar neutrino oscillation phenomenology at the end of 2002 in the light of the SNO and KamLAND results. We first present the allowed areas obtained from global solar analysis and demonstrate the preference of the solar data towards the Large-Mixing-Angle (LMA) MSW solution. A clear confirmation in favor of the

Physics of solar-like oscillations [PDF]
Solar Physics, 2004 AbstractThe physics of solar and stellar oscillations determine their observable characteristics. I provide a brief overview of the properties of solar-like oscillations, excited by stochastic processes, in other stars. In addition, I consider the current state of investigations of such oscillations, as well as the prospects for an improved ...

The Astrophysical Journal, 2023 The shear flow influences the stability of magnetohydrodynamic (MHD) waves. In the presence of a dissipation mechanism, flow shear may induce an MHD wave instability below the threshold of the Kelvin–Helmholtz instability, which is called dissipative ...
