The Alignment of High-resolution Solar Prominence Images Observed by the New Vacuum Solar Telescope [PDF]
The Astrophysical JournalHigh spatial resolution observation of solar prominence is an important observation subject of the New Vacuum Solar Telescope (NVST). While the current level of observation and image reconstruction technologies for solar prominences are advanced, a ...

Evidence for a Magnetic Flux Rope in Observations of a Solar Prominence-Cavity System
Frontiers in Astronomy and Space Sciences, 2016 Coronal cavities are regions of low coronal emission that usually sit above solar prominences. These systems can exist for days or months before erupting.

Conditions for Solar Prominence Formation Triggered by Single Localized Heating
The Astrophysical JournalWe performed numerical simulations to study mechanisms of solar prominence formation triggered by a single heating event. In the widely accepted “chromospheric-evaporation condensation” model, localized heating at footpoints of a coronal loop drives ...

Two-fluid simulations of Rayleigh-Taylor instability in a magnetized solar prominence thread [PDF]
Astronomy & Astrophysics, 2021 Solar prominences are formed by partially ionized plasma with inter-particle collision frequencies generally warranting magnetohydrodynamic treatment.

A prominence eruption from the Sun to the Parker Solar Probe with multi-spacecraft observations [PDF]
Frontiers in Astronomy and Space Sciences, 2023 In the early hours of 2021 April 25, the Solar Probe Cup on board Parker Solar Probe registered the passage of a solar wind structure characterized by a clear and constant He2+/H+ density ratio above 6% during three hours.

The influence of flux rope heating models on solar prominence formation [PDF]
Astronomy & Astrophysics, 2022 Aims. We begin by exploring the influence of two classes of commonly adopted heating models on the formation behaviour of solar prominences. These models consider either an exponential variation dependent on height alone, or local density and magnetic ...

First high resolution interferometric observation of a solar prominence with ALMA [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2022 We present the first observation of a solar prominence at 84 − 116 GHz using the high resolution interferometric imaging of ALMA. Simultaneous observations in Hα from Białkaw Observatory and with SDO/AIA reveal similar prominence morphology to the ALMA

A Unified Model of Solar Prominence Formation [PDF]
Astrophysical Journal Letters, 2021 Several mechanisms have been proposed to account for the formation of solar prominences or filaments, among which direct injection and evaporation–condensation models are the two most popular ones.

Solar prominence diagnostics from non-LTE modelling of Mg II h&k line profiles [PDF]
Astronomy & Astrophysics, 2021 Aims. We investigate a new method to for obtaining the plasma parameters of solar prominences observed in the Mg II h&k spectral lines by comparing line profiles from the IRIS satellite to a bank of profiles computed with a one-dimensional non-local ...
