Coronal Jets, and the Jet-CME Connection

Alphonse C. Sterling

Solar coronal jets have been observed in detail since the early 1990s. While it is clear that these jets are magnetically driven, the details of the driving process has recently be…

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…

Measuring and modeling the rate of separator reconnection between an emerging and existing active region

Marika I. McCarthy, Dana W. Longcope, Anna Malanushenko +1

Magnetic reconnection occurs when new flux emerges into the corona and becomes incorporated into the existing coronal field. A new active region (AR) emerging in the vicinity of an…

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…

The High-Resolution Coronal Imager, Flight 2.1

Laurel A. Rachmeler, Amy R. Winebarger, Sabrina L. Savage +49

The third flight of the High-Resolution Coronal Imager (Hi-C 2.1) occurred on May 29, 2018, the Sounding Rocket was launched from White Sands Missile Range in New Mexico. The instr…

Solar Active Region Heating Diagnostics from High Temperature Emission using the Marshall Grazing Incidence X-ray Spectrometer (MaGIXS)

P. S. Athiray, Amy R. Winebarger, Will T. Barnes +7

The relative amount of high temperature plasma has been found to be a useful diagnostic to determine the frequency of coronal heating on sub-resolution structures. When the loops a…

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…

Signatures of the non-Maxwellian -distributions in optically thin line spectra. II. Synthetic Fe XVII--XVIII X-ray coronal spectra and predictions for the Marshall Grazing-Incidence X-ray Spectrometer (MaGIXS)

Jaroslav Dudik, Elena Dzifcakova, Giulio Del Zanna +4

We investigated the possibility of diagnosing the degree of departure from the Maxwellian distribution using the Fe XVII - Fe XVIII spectra originating in plasmas in collisional io…

Multi-component Decomposition of Astronomical Spectra by Compressed Sensing

Mark C. M. Cheung, Bart De Pontieu, Juan Martınez-Sykora +9

The signal measured by an astronomical spectrometer may be due to radiation from a multi-component mixture of plasmas with a range of physical properties (e.g. temperature, Doppler…
