Fine Structures of Tiny Quiet Sun Jets Observed by Solar Orbiter and Big Bear Solar Observatory

Jeongwoo Lee, Dana Longcope, Junmu Youn +3

We present the first joint high-resolution observations of small-scale EUV jets using Solar Orbiter(SolO)'s Extreme Ultraviolet Imager and High Resolution Imager (HRI) and H ima…

High-resolution Observation of Mini-Filament Eruptions Near Coronal Hole Boundary and Their Response in Solar Corona

Nengyi Huang, Haimin Wang

We investigated mini-filament (MF) eruptions near coronal hole (CH) boundaries to explore their role in coronal dynamics and their potential contributions to the solar wind. Using…

He I 10830 Å Dimming During Solar Flares, I. The Crucial Role of Non-Thermal Collisional Ionisations

Graham S. Kerr, Yan Xu, Joel C. Allred +4

While solar flares are predominantly characterised by an intense broadband enhancement to the solar radiative output, certain spectral lines and continua will, in theory, exhibit f…

Comparison of Enhanced Absorption in He I 10830 Å in Observations and Modeling During the Early Phase of a Solar Flare

Nengyi Huang, Viacheslav M. Sadykov, Yan Xu +2

The He I 10830 Å triplet is a very informative indicator of chromospheric activities as the helium is the second most abundant element in the solar atmosphere. Taking advantage of…

Collective Study of Polar Crown Filaments in the Past Four Solar Cycles

Yan Xu, Werner Potzi, Hewei Zhang +3

Polar Crown Filaments (PCFs) form above the magnetic polarity inversion line, which separates the unipolar polar fields and the nearest dispersed fields from trailing part of activ…

Relationship between Intensity of White-Light Flares and Proton Flux of Solar Energetic Particles

Nengyi Huang, Yan Xu, Haimin Wang

Solar energetic particles (SEPs), including protons and heavy ions, are believed to be accelerated either by CME shock or by magnetic reconnection. The latter also produces solar f…
