Special Issue Information

Dear Colleagues,

Solar filaments or prominences are prominent magnetic structures in the solar corona whose dynamics are central to our understanding of solar activity. The study of oscillations within these magnetic structures has emerged as a cornerstone of modern solar physics. These oscillations not only serve as a powerful diagnostic tool for probing local plasma and magnetic field conditions (i.e., solar coronal seismology) but are also intimately linked to the catastrophic loss of equilibrium that leads to solar eruptions, the primary drivers of space weather. Understanding how wave modes are excited, how they propagate, and how they may grow into eruptive instabilities is a key challenge that this Special Issue will address.

This Special Issue of Universe is dedicated to gathering the latest advances in the study of filament or prominence oscillations and their profound implications. We welcome submissions of original research and review articles that focus primarily on this theme. Suggested topics include, but are not limited to, the following:

  • Theory, observation, and simulation of MHD wave modes in solar filaments;
  • Filament seismology: using oscillations to diagnose plasma and magnetic field properties;
  • Excitation and damping mechanisms of various filament oscillation modes;
  • The role of large-amplitude oscillations in triggering filament instabilities and eruptions;
  • Observational evidence of oscillations as precursors to solar flares and CMEs;
  • The interplay between filament thermal properties, fine structures, and wave propagation;
  • Novel observational techniques and data analysis methods for studying filament oscillations.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In this paper, we investigate the thread oscillations in a quiescent prominence observed by New Vacuum Solar Telescope at the Hα line center on 17 April 2024. Each individual thread is traced by the local maximum intensity on the time–distance maps. Although there are numerous threads in this prominence, 24 oscillating threads are identified at eight slits parallel to the solar surface. A sinusoidal function is used to fit them, and about 1.5 cycles of oscillations and a mean period of 27.7 min are detected. We find that all these 24 threads display the oscillation with almost a constant amplitude with an average value of about 0.92 Mm, with no damping or expansion during their lifetimes. Furthermore, we find the oscillations at different positions on a same thread almost have a similar period of 88.7 min in phase, which indicates that the thread oscillations could be triggered by a standing-type wave. Using the typical parameters in the prominence, the magnetic field strength (B) is estimated in the range of 4 G ≤ B ≤ 21 G, which is consistent with the previous results. Our findings would provide the clues for the thread oscillation mechanism in the prominence. Full article
