Prominence eruption observed in He II 304 AA up to >6 R_\odot by EUI/FSI aboard Solar Orbiter [PDF]
Astronomy & Astrophysics, 2022 We report observations of a unique, large prominence eruption that was observed in the He II 304 {\AA} passband of the the Extreme Ultraviolet Imager/Full Sun Imager telescope aboard Solar Orbiter on 15-16 February 2022. Observations from several vantage

Prominence observations with ALMA
Frontiers in Astronomy and Space Sciences, 2022 This review comes at the time when ALMA successfully obtained the first regular observations of both a prominence and a filament. These observations have a spatial resolution of 1-2 arcsec, far better than previous prominence observations in the mm/sub ...

Coronal mass ejection followed by a prominence eruption and a plasma blob as observed by Solar Orbiter [PDF]
Astronomy & Astrophysics, 2022 On February 12, 2021 two subsequent eruptions occurred above the West limb, as seen along the Sun-Earth line. The first event was a typical slow Coronal Mass Ejection (CME), followed $\sim 7$ hours later by a smaller and collimated prominence eruption ...

Nonlinear Fast Magnetosonic Waves in Solar Prominence Pillars
The Astrophysical Journal, 2023 We investigate the properties of nonlinear fast magnetosonic (NFM) waves in a solar prominence, motivated by recent high-resolution and high-cadence Hinode/Solar Optical Telescope (SOT) observations of small-scale oscillations in a prominence pillar.

Three-dimensional MHD Simulations of Solar Prominence Oscillations in a Magnetic Flux Rope [PDF]
, 2018 Solar prominences are subject to all kinds of perturbations during their lifetime, and frequently demonstrate oscillations. The study of prominence oscillations provides an alternative way to investigate their internal magnetic and thermal structures ...

First Metis Detection of the Helium D3 Line Polarization in a Large Eruptive Prominence
The Astrophysical Journal Letters, 2023 Metis on board Solar Orbiter is the space coronagraph developed by an Italian–German–Czech consortium. It is capable of observing solar corona and various coronal structures in the visible-light (VL) and UV (hydrogen Ly α ) channels simultaneously for ...

Finding the Critical Decay Index in Solar Prominence Eruptions [PDF]
Astrophysical Journal, 2019 The background field is assumed to play a prime role in erupting structures like prominences. In the flux rope models, the critical decay index (nc) is a measure of the rate at which background field intensity decreases with height over the flux rope or ...

Differences between Doppler velocities of ions and neutral atoms in a solar prominence [PDF]
, 2017 In astrophysical systems with partially ionized plasma the motion of ions is governed by the magnetic field while the neutral particles can only feel the magnetic field's Lorentz force indirectly through collisions with ions.

Simultaneous Horizontal and Vertical Oscillation of a Quiescent Filament Observed by CHASE and SDO
The Astrophysical Journal, 2023 In this paper, we present the imaging and spectroscopic observations of the simultaneous horizontal and vertical large-amplitude oscillation of a quiescent filament triggered by an extreme-ultraviolet (EUV) wave on 2022 October 2.
