Latitude migration of solar filaments [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2010
The Carte Synoptique catalogue of solar filaments from March 1919 to December 1989, corresponding to complete cycles 16 to 21 is utilized to show latitudinal migration of filaments at low latitudes (less than 50 deg), and the latitudinal drift of solar filaments in each hemisphere in each cycle of the time interval is compared with the corresponding ...

SYMPATHETIC SOLAR FILAMENT ERUPTIONS [PDF]

open access: yesThe Astrophysical Journal Letters, 2016
ABSTRACT The 2015 March 15 coronal mass ejection as one of the two that together drove the largest geomagnetic storm of solar cycle 24 so far was associated with sympathetic filament eruptions. We investigate the relations between the different filaments involved in the eruption.

Sympathetic Partial Filament Eruptions Caused by the Interaction between Two Nearby Filaments

open access: yesThe 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 Formation of a U-shaped Filament Due to the Successive Magnetic Reconnection between a Filament and Its Nearby Chromospheric Fibrils

open access: yesThe Astrophysical Journal, 2023
Although magnetic reconnection plays a key role in the formation of a solar filament, the detailed formation process is still ambiguous. Combining the observational data from the New Vacuum Solar Telescope and the Solar Dynamics Observatory, we analyzed ...

Network Jets as the Driver of Counter-streaming Flows in a Solar Filament/Filament Channel [PDF]

open access: yesThe Astrophysical Journal Letters, 2020
Abstract Counter-streaming flows in a small (100″ long) solar filament/filament channel are directly observed in high-resolution Solar Dynamics Observatory (SDO)/Atmospheric Imaging Assembly (AIA) extreme-ultraviolet (EUV) images of a region of enhanced magnetic network.

The Kinematical Behavior of Solar Eruptive Filaments Affected by the Poloidal Magnetic Field

open access: yesThe Astrophysical Journal
Kinematics of solar eruptive filaments is one of the important diagnostic parameters for predicting whether solar eruptions would induce geomagnetic storms.

3D Printing Innovations in Polymeric Porous and Patterned Architecture

open access: yesAdvanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

A Unified Model of Solar Prominence Formation with Self-consistent Heating

open access: yesThe Astrophysical Journal
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.
