Solar Flare Prediction with the Hybrid Deep Convolutional Neural Network

Astrophysical Journal, 2019
We propose a hybrid Convolutional Neural Network (CNN) model (Model 2) and modify a popular CNN model (Model 1) to predict multiclass solar flare occurrence within 24 hr.

Two Types of Solar Confined Flares [PDF]

arXiv, 2019
With the aim of understanding the physical mechanisms of confined flares, we selected 18 confined flares during 2011-2017, and classified the confined flares into two types based on their different dynamic properties and magnetic configurations. "Type I" of confined flares are characterized by slipping reconnection, strong shear, and stable filament ...

Electric current in flares ribbons: observations and 3D standard model

, 2014
We present for the first time the evolution of the photospheric electric currents during an eruptive X-class flare, accurately predicted by the standard 3D flare model.

Infection-Associated Flares in Systemic Lupus Erythematosus

Pathogens
Systemic lupus erythematosus (SLE) is characterised by generalised immune dysfunction, including infection susceptibility. Infection-associated flares (IAFs) are common and might rapidly self-resolve, paralleling infection resolution, but their specific ...

The Giant X-ray Flare of GRB 050502B: Evidence for Late-Time Internal Engine Activity

, 2005
Until recently, X-ray flares during the afterglow of gamma ray bursts (GRBs) were a rarely detected phenomenon, thus their nature is unclear. During the afterglow of GRB 050502B, the largest X-ray flare ever recorded rose rapidly above the afterglow ...

Statistical Analysis and the OPEA Model of the White-Light Flares Occurring on Kr\"uger 60B (DO Cep)

, 2011
In this study, new observations and some results of statistical analyses are presented. The largest flare data set of DO Cep in the literature has been obtained with 89 flares detected in 67.61 hours of U-band flare patrol. First of all, the observations

Drag Effect of Kompsat-1 During Strong Solar and Geomagnetic Activity [PDF]

Journal of Astronomy and Space Sciences, 2007
In this paper, we analyze the orbital variation of the KOrea Multi-Purpose SATellite-1(KOMPSAT-1) in a strong space environment due to satellite drag by solar and geomagnetic activities.

Modelling blazar flaring using a time-dependent fluid jet emission model - an explanation for orphan flares and radio lags [PDF]

, 2017
Blazar jets are renowned for their rapid violent variability and multiwavelength flares, however, the physical processes responsible for these flares are not well understood. In this paper we develop a time-dependent inhomogeneous fluid jet emission model for blazars.
