Quantifying the Toroidal Flux of Pre-existing Flux Ropes of CMEs

C. Xing, X. Cheng, Jiong Qiu +3

In past decades, much progress has been achieved on the origin and evolution of coronal mass ejections (CMEs). In-situ observations of the counterparts of CMEs, especially magnetic…

Hi-C 2.1 Observations of Small-Scale Miniature-Filament-Eruption-Like Cool Ejections in Active Region Plage

Alphonse C. Sterling, Ronald L. Moore, Navdeep K. Panesar +5

We examine 172 Ang ultra-high-resolution images of a solar plage region from the Hi-C 2.1 ("Hi-C") rocket flight of 2018 May 29. Over its five-minute flight, Hi-C resolves a pletho…

Heliospheric structure as revealed by the 3 -- 88 keV H ENA spectra

A. Czechowski, M. Bzowski, J. M. Sokół +8

Energetic neutral atoms (ENA) are an important tool for investigating the structure of the heliosphere. Recently, it was observed that fluxes of ENAs (with energy 55 keV) com…

Hi-C 2.1 Observations of Jetlet-like Events at Edges of Solar Magnetic Network Lane

Navdeep K. Panesar, Alphonse C. Sterling, Ronald L. Moore +15

We present high-resolution, high-cadence observations of six, fine-scale, on-disk jet-like events observed by the High-resolution Coronal Imager 2.1 (Hi-C 2.1) during its sounding-…

Fine-scale explosive energy release at sites of prospective magnetic flux cancellation in the core of the solar active region observed by Hi-C 2.1, IRIS and SDO

Sanjiv K. Tiwari, Navdeep K. Panesar, Ronald L. Moore +14

The second Hi-C flight (Hi-C2.1) provided unprecedentedly-high spatial and temporal resolution (250km, 4.4s) coronal EUV images of Fe IX/X emission at 172 Å, of AR 12712 on 2…

Three-dimensional magnetic field structure of a flux emerging region in the solar atmosphere

Rahul Yadav, J. de la Cruz Rodríguez, C. J. Díaz Baso +4

We analyze high-resolution spectropolarimetric observations of a flux emerging region (FER) in order to understand its magnetic and kinematic structure. Our spectropolarimetric obs…

Godbillon-Vey Helicity and Magnetic Helicity in Magnetohydrodynamics

G. M. Webb, A. Prasad, S. C. Anco +1

The Godbillon-Vey invariant occurs in homology theory, and algebraic topology, when conditions for a co-dimension 1, foliation of a 3D manifold are satisfied. The magnetic Godbillo…

Magnetic Flux Cancellation as the Trigger Mechanism of Solar Coronal Jets

Riley A. McGlasson, Navdeep K. Panesar, Alphonse C. Sterling +1

Coronal jets are transient narrow features in the solar corona that originate from all regions of the solar disk: active regions, quiet sun, and coronal holes. Recent studies indic…

Effect of Star Rotation Rates on the Characteristics of Energetic Particle Events

Shuai Fu, Yong Jiang, Vladimir Airapetian +3

Recent detection of superflares on solar-type stars by Kepler mission raised a possibility that they can be associated with energetic coronal mass ejections (CMEs) and energetic pa…
