Magneto-seismology of solar atmospheric loops by means of longitudinal oscillations

open access: yes, 2012
There is increasingly strong observational evidence that slow magnetoacoustic modes arise in the solar atmosphere. Solar magneto-seismology is a novel tool to derive otherwise directly un-measurable properties of the solar atmosphere when ...

Observations of apparent superslow wave propagation in solar prominences [PDF]

open access: yes, 2017
Phase mixing of standing continuum Alfv\'en waves and/or continuum slow waves in atmospheric magnetic structures such as coronal arcades can create the apparent effect of a wave propagating across the magnetic field.

Diagnostics of the solar coronal plasmas by magnetohydrodynamic waves: magnetohydrodynamic seismology

open access: yesReviews of Modern Plasma Physics
AbstractMacroscopic wave and oscillatory phenomena ubiquitously detected in the plasma of the corona of the Sun are interpreted in terms of magnetohydrodynamic theory. Fast and slow magnetoacoustic waves are clearly distinguished in observations. Properties of coronal magnetohydrodynamic waves are determined by local parameters of the plasma, including

Transverse kink oscillations of expanding coronal loops [PDF]

open access: yes, 2012
We investigate the nature of transverse kink oscillations of loops expanding through the solar corona and how can oscillations be used to diagnose the plasma parameters and the magnetic field.

Bayesian Coronal Seismology

open access: yes, 2017
In contrast to the situation in a laboratory, the study of the solar atmosphere has to be pursued without direct access to the physical conditions of interest. Information is therefore incomplete and uncertain and inference methods need to be employed to

Magnetohydrodynamic Waves in Multi-Layered Asymmetric Waveguides: Solar Magneto-Seismology Theory and Application

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Diagnosing the solar atmospheric plasma is one of the major challenges in solar physics. Magnetohydrodynamic (MHD) waves, by means of applying the powerful concept of solar magneto-seismology (SMS), provide a tool to obtain diagnostic insight into the ...

Measurements of the Solar Coronal Magnetic Field Based on Coronal Seismology with Propagating Alfvénic Waves: Forward Modeling

open access: yesResearch in Astronomy and Astrophysics
Abstract Recent observations have demonstrated the capability of mapping the solar coronal magnetic field using the technique of coronal seismology based on the ubiquitous propagating Alfvénic/kink waves through imaging spectroscopy.

MHD Seismology of a Coronal Loop System by the First Two Modes of Standing Kink Waves

open access: yes, 2014
We report the observation of the first two harmonics of the horizontally polarized kink waves excited in a coronal loop system lying at south-east of AR 11719 on 2013 April 11.

Analysis of Ionospheric Disturbances Near 120°E in the Asia‐Pacific Sector During the May 2024 Superstorm Using Multi‐Instrument Observations

open access: yesSpace Weather, Volume 24, Issue 2, February 2026.
Abstract On 10 May 2024, a severe G5 geomagnetic storm—the most intense of solar cycle 25—significantly disturbed the global ionosphere. This study presents a comprehensive analysis using multi‐instrument observations, including ground‐based measurements from BDS‐GEO total electron content (TEC), digital ionosondes, and magnetometers; model outputs ...
