Polarisation of decayless kink oscillations of solar coronal loops

open access: yesNature Communications, 2023
Decayless kink oscillations of plasma loops in the solar corona may contain an answer to the enigmatic problem of solar and stellar coronal heating. The polarisation of the oscillations gives us a unique information about their excitation mechanisms and ...

Prominence oscillations

open access: yesLiving Reviews in Solar Physics, 2018
Prominences are intriguing, but poorly understood, magnetic structures of the solar corona. The dynamics of solar prominences has been the subject of a large number of studies, and of particular interest is the study of prominence oscillations.

Solar Oscillations [PDF]

open access: yesAIP Conference Proceedings, 2009
In recent years solar oscillations have been studied in great detail, both observationally and theoretically; so, perhaps, the Sun currently is the best understood pulsating star. The observational studies include long, almost uninterrupted series of oscillation data from the SOHO spacecraft and ground-based networks, GONG and BiSON, and more recently,

Performance of the Birmingham Solar-Oscillations Network (BiSON) [PDF]

open access: yes, 2015
The Birmingham Solar-Oscillations Network (BiSON) has been operating with a full complement of six stations since 1992. Over 20 years later, we look back on the network history.

Validation of solar-cycle changes in low-degree helioseismic parameters from the Birmingham Solar-Oscillations Network [PDF]

open access: yes, 2015
We present a new and up-to-date analysis of the solar low-degree $p$-mode parameter shifts from the Birmingham Solar-Oscillations Network (BiSON) over the past 22 years, up to the end of 2014.

Low-frequency oscillations while magnetic storms as a tool to determine the types of solar plasma flows [PDF]

open access: yesE3S Web of Conferences, 2020
Comparison of wavelet spectrum (skeletons) local maxima for disturbed components of solar plasma flow parameters and geomagnetic field disturbances recorded along the meridional station chain during geomagnetic storm intervals is performed in the range ...

Effects of granulation on the visibility of solar oscillations [PDF]

open access: yes, 2015
Context. The interaction of solar oscillations with near surface convection is poorly understood. These interactions are likely the cause of several problems in helio- and astero-seismology, including the so-called surface effect and apparently ...

Filtering Solar-Like Oscillations for Exoplanet Detection in Radial Velocity Observations [PDF]

open access: yesAstronomical Journal, 2019
Cool main-sequence, subgiant, and red giant stars all show solar-like oscillations, pulsations that are excited and intrinsically damped by near-surface convection.

Intermediate Degree Solar Oscillations [PDF]

open access: yesSymposium - International Astronomical Union, 1988
Spectra of solar intensity oscillations in the degree range ℓ = 20–98 were obtained with a 92% duty cycle over a 50 hour period from the geographic South Pole. After correction for solar rotation, the spectra have been averaged over azimuthal order m and fit with Lorentzian functions to provide values of background noise, amplitude, frequency and line ...

Five-Minute Solar Oscillations and Ion-Cyclotron Waves in the Solar Wind [PDF]

open access: yes, 2015
We study the possible impact of the photospheric five-minute oscillations on the ion-cyclotron waves in the solar wind. We proceed from the assumption that the ion-cyclotron waves in the solar wind experience a modulation with a characteristic period of ...
