GONG Catalog of Solar Filament Oscillations Near Solar Maximum [PDF]
Abstract We have cataloged filament oscillations from the Global Oscillation Network Group Hα network data during several months near the maximum of solar cycle 24 (2014 January–June).

A Breakout Model for Solar Coronal Jets with Filaments [PDF]
Recent observations have revealed that many solar coronal jets involve the eruption of miniature versions of large-scale filaments. Such “mini-filaments” are observed to form along the polarity inversion lines of strong, magnetically bipolar regions ...

The Phase Shifts of the Paired Wings of Butterfly Diagrams
Sunspot groups observed by Royal Greenwich Observatory/US Air Force/NOAA from May 1874 to November 2008 and the Carte Synoptique solar filaments from March 1919 to December 1989 are used to investigate the relative phase shift of the paired wings of ...

Automated High-Precision Recognition of Solar Filaments Based on an Improved U2-Net
Solar filaments are a significant solar activity phenomenon, typically observed in full-disk solar observations in the H-alpha band. They are closely associated with the magnetic fields of solar active regions, solar flare eruptions, and coronal mass ...

Evolution of helicity in NOAA 10923 over three consecutive solar rotations
We have studied the evolution of magnetic helicity and chirality in an active region over three consecutive solar rotations. The region when it first appeared was named NOAA10923 and in subsequent rotations it was numbered NOAA 10930, 10935 and 10941. We

The Kinematical Behavior of Solar Eruptive Filaments Affected by the Poloidal Magnetic Field
Kinematics of solar eruptive filaments is one of the important diagnostic parameters for predicting whether solar eruptions would induce geomagnetic storms.

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation
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.

A Unified Model of Solar Prominence Formation with Self-consistent Heating
Several models have been proposed to explain the formation of solar prominences, among which the evaporation–condensation model and the direct injection model are the most popular ones.

Chirality of Intermediate Filaments and Magnetic Helicity of Active Regions
Filaments which form either between or around active regions (ARs) are called intermediate filaments. In spite of various theoretical studies, the origin of the chirality of filaments is still uncovered.
