TORNADO-LIKE EVOLUTION OF A KINK-UNSTABLE SOLAR PROMINENCE [PDF]
, 2016 We report on the tornado-like evolution of a quiescent prominence on 2014 November 1. The eastern section of the prominence first rose slowly, transforming into an arch-shaped structure as high as ∼150 Mm above the limb; the arch then writhed moderately ...

Observations of the Kelvin–Helmholtz Instability Driven by Dynamic Motions in a Solar Prominence [PDF]
Astrophysical Journal, 2018 Prominences are incredibly dynamic across the whole range of their observable spatial scales, with observations revealing gravity-driven fluid instabilities, waves, and turbulence.

Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. I. Discovery of Prominence Eruptions Associated with Superflares [PDF]
Astrophysical Journal, 2023 Young solar-type stars frequently produce superflares, serving as a unique window into the young Sun-Earth environments. Large solar flares are closely linked to coronal mass ejections (CMEs) associated with filament/prominence eruptions, but ...

Gravitational instability of solar prominence threads [PDF]
, 2021 Prominence threads are dense and cold structures lying on curved magnetic fields that can be suspended in the solar atmosphere against gravity. The gravitational stability of threads, in the absence of non-ideal effects, is comprehensively investigated ...

Two-fluid simulations of Rayleigh-Taylor instability in a magnetized solar prominence thread [PDF]
Astronomy & Astrophysics, 2020 Solar prominences are formed by partially ionized plasma with inter-particle collision frequencies, which generally warrant magnetohydrodynamic treatment.

FINE MAGNETIC STRUCTURE AND ORIGIN OF COUNTER-STREAMING MASS FLOWS IN A QUIESCENT SOLAR PROMINENCE [PDF]
, 2015 We present high-resolution observations of a quiescent solar prominence that consists of a vertical and a horizontal foot encircled by an overlying spine and has ubiquitous counter-streaming mass flows.

Doppler-velocity Drifts Detected in a Solar Prominence
Astrophysical Journal, 2022 We analyzed multiline observations of a quiescent prominence from the slit spectrograph located at the Ondřejov Observatory. Dopplergrams and integrated intensity maps of the whole prominence were obtained from observations in six spectral lines: Ca ii H,

Dynamics of Descending Knots in a Solar Prominence and Their Possible Contributions to the Heating of the Local Corona [PDF]
Astrophysical Journal, 2020 The knots in solar prominences are often observed to fall with nearly constant velocity, but the associated physical mechanism is currently not well understood.

Solar Prominence Bubble and Plumes Caused By an Eruptive Magnetic Flux Rope
Astrophysical Journal Letters, 2021 Prominence bubbles and plumes often form near the lower prominence–corona boundary. They are believed to play an important role in mass supply and evolution of solar prominences. However, how they form is still an open question. In this Letter we present

Model comparison for the density structure along solar prominence threads [PDF]
, 2015 Context. Quiescent solar prominence fine structures are typically modelled as density enhancements, called threads, which occupy a fraction of a longer magnetic flux tube.
