Observing the release of twist by magnetic reconnection in a solar filament eruption [PDF]

Nature Communications, 2016
AbstractMagnetic reconnection is a fundamental process of topology change and energy release, taking place in plasmas on the Sun, in space, in astrophysical objects and in the laboratory. However, observational evidence has been relatively rare and typically only partial.

Detection of volcanic, solar and greenhouse gas signals in paleo-reconstructions of Northern Hemispheric temperature [PDF]

, 2003
We apply a multiple regression method to estimate the response to anthropogenic and natural climate forcings simultaneously from a number of paleo-reconstructions of Northern Hemispheric average temperature. These long records (600 to 1000 years) provide

Small-scale motions in solar filaments as the precursors of eruptions [PDF]

Publications of the Astronomical Society of Japan, 2019
Abstract Filaments, the dense cooler plasma floating in the solar corona supported by magnetic fields, generally exhibit certain activations before they erupt. In our previous study (Seki et al. 2017, ApJ, 843, L24), we observed that the standard deviation of the line-of-sight (LOS) velocities of the small-scale motions in a filament ...

Hinode Observations of the Onset Stage of a Solar Filament Eruption [PDF]

Publications of the Astronomical Society of Japan, 2007
Abstract We used Hinode X-Ray Telescope (XRT) and Solar Optical Telescope (SOT) filtergraph (FG) Stokes-V magnetogram observations, to study the early onset of a solar eruption that includes an erupting filament that we observe in TRACE EUV images.

ERUPTION OF A SOLAR FILAMENT CONSISTING OF TWO THREADS

The Astrophysical Journal, 2012
The trigger and driving mechanism for the eruption of a filament consisting of two dark threads was studied with unprecedented high cadence and resolution of He II 304 angstrom observations made by the Atmospheric Imagining Assembly (AIA) on board the Solar Dynamics Observatory (SDO) and the observations made by the Solar Magnetic Activity Research ...

SOLAR FILAMENT MATERIAL OSCILLATIONS AND DRAINAGE BEFORE ERUPTION [PDF]

The Astrophysical Journal, 2014
Both large-amplitude longitudinal (LAL) oscillations and material drainage in a solar filament are associated with the flow of material along the filament axis, often followed by an eruption. However, the relationship between these two motions and a subsequent eruption event is poorly understood.

Reconfiguration and Eruption of a Solar Filament by Magnetic Reconnection with an Emerging Magnetic Field

The Astrophysical Journal, 2022
Abstract Both observations and simulations suggest that the solar filament eruption is closely related to magnetic flux emergence. It is thought that the eruption is triggered by magnetic reconnection between the filament and the emerging flux. However, the details of such a reconnection are rarely presented. In this study, we report the

Beyond the Martin Curve: A Mechanistic Yet Simple Model for Dynamic Ocean Particulate Organic Carbon Fluxes

Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Biological processes contribute to ocean carbon storage, playing a critical role in the global carbon cycle by maintaining lower atmospheric CO2 ${\text{CO}}_{2}$ levels. A major pathway is the gravitational sinking of particulate organic carbon (POC), yet how POC fluxes change in a warming ocean remains uncertain due, in part, to high ...

Plasma Brightenings in a Failed Solar Filament Eruption

The Astrophysical Journal, 2017
Abstract Failed filament eruptions are solar eruptions that are not associated with coronal mass ejections. In a failed filament eruption, the filament materials usually show some ascending and falling motions as well as generating bright EUV emissions.
