Magnetic reconnection is a key mechanism involved in solar eruptions and is also a prime
possibility to heat the low corona to millions of degrees. Here, we present ultra-high …

Impulsive solar energetic particle events are widely believed to be due to the prompt escape
into the interplanetary medium of flare-accelerated particles produced by solar eruptive …

Solar flares are an impulsive increase of emissions as a result of impetuous release of
magnetic free energy. This paper will present the recent progress on circular-ribbon flares …

Context. While non-potential (free) magnetic energy is a necessary element of any active
phenomenon in the solar corona, its role as a marker of the trigger of the eruptive process …

We analyze a unique event with an M1. 8 confined circular-ribbon flare on 2016 February
13, with successive formations of two circular ribbons at the same location. The flare had two …

Fan-spine is a special topology in solar atmosphere and is closely related to magnetic null
point, as well as circular-ribbon flares, which can provide important information for …

We present a detailed analysis of a confined filament eruption and jet associated with a C1.
5 class solar flare. Multi-wavelength observations from the Global Oscillations Network …

Magnetic reconnection is widely accepted to be a major contributor to nonthermal particle
acceleration in the solar atmosphere. In this paper we investigate particle acceleration …

Magnetic flux ropes play a key role in triggering solar flares in the solar atmosphere. In this
paper, we investigate the evolution of NOAA Active Region 12268 within 36 hr from 2015 …

Five decades of satellite data confirm that the solar wind contains many boundaries
separating flow with distinct magnetic and plasma properties. Some speculate the …
