Why torus-unstable solar filaments experience failed eruption? [PDF]
The Astrophysical Journal Letters, 2019 To investigate the factors that control the success and/or failure of solar eruptions, we study the magnetic field and 3-Dimensional (3D) configuration of 16 filament eruptions during 2010 July - 2013 February.

Solar Filament Eruptions in H α Doppler Velocity
The Astrophysical Journal, 2023 We use observations taken with a novel solar telescope spectroheliograph to investigate the association between the early filament rise and coronal mass ejections (CMEs).

Sympathetic Partial Filament Eruptions Caused by the Interaction between Two Nearby Filaments
The Astrophysical Journal, 2023 To better understand the physical connections in sympathetic solar eruptions, we investigated the interaction between two nearby filaments and their successive partial eruptions in the active region (AR) NOAA 12866 on 2021 September 9 by using data from ...

The Astrophysical Journal, 2023 How structures, e.g., magnetic loops, in the upper atmosphere, i.e., the transition region and corona, are heated and sustained is one of the major unresolved issues in solar and stellar physics.

The Impulsive Acceleration of a Solar Filament Eruption Associated with a B-class Flare
The Astrophysical Journal, 2023 The eruption of magnetic flux ropes (MFRs), often taking filaments together, leads to coronal mass ejections (CMEs). Theoretical studies propose that both the resistive magnetic reconnection and the ideal instability of an MFR system can release magnetic-

Quantification of the Writhe Number of the Evolution of Solar Filament Axes
The Astrophysical Journal, 2023 Solar filament eruptions often show complex and dramatic geometric deformation that is highly relevant to the underlying physical mechanism triggering the eruptions.

Initiation and Early Kinematic Evolution of Solar Eruptions
, 2020 We investigate the initiation and early evolution of 12 solar eruptions, including six active region hot channel and six quiescent filament eruptions, which were well observed by the \textsl{Solar Dynamics Observatory}, as well as by the \textsl{Solar ...

Two successive partial mini-filament confined ejections [PDF]
, 2019 Active region (AR) NOAA 11476 produced a series of confined plasma ejections, mostly accompanied by flares of X-ray class M, from 08 to 10 May 2012. The structure and evolution of the confined ejections resemble that of EUV surges; however, their origin ...
