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 ...

Evolution of Elemental Abundances in Hot Active Region Cores from Chandrayaan-2 XSM Observations
The Astrophysical Journal, 2023 The first ionization potential (FIP) bias, whereby elemental abundances for low-FIP elements in different coronal structures vary from their photospheric values and may also vary with time, has been widely studied.

The Astrophysical Journal, 2023 The nonassociation of coronal mass ejections with high energetic flares is sparse. For this reason, the magnetic conditions required for the confinedness of major flares is a topic of active research.

Physics of outflows near solar active regions [PDF]
Annales Geophysicae, 2015 Hinode/EIS observations have revealed outflows near active regions which remain unexplained. An outflow region observed by the EUV Imaging Spectrometer (EIS) that appears slightly redshifted at low temperatures and blueshifted at higher temperatures ...

Magnetic Reconnection between a Solar Jet and a Filament Channel
The Astrophysical JournalThe solar corona is highly structured by bunches of magnetic field lines forming either loops, or twisted flux ropes representing prominences/filaments, or very dynamic structures such as jets.

The Astrophysical JournalUsing synoptic maps, we analyzed the relationship between active longitudes, the most populated longitudes of energetic flares, the distribution of magnetically complex active regions, and the preferred locations of those that produced the largest flares.

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation
Advanced Engineering Materials, EarlyView.This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.
