Onset of a Large Ejective Solar Eruption from a Typical Coronal-Jet-Base Field Configuration
Navin Chandra Joshi, Alphonse C. Sterling, Ronald L. Moore +2
Utilizing multiwavelength observations and magnetic field data from SDO/AIA, SDO/HMI, GOES and RHESSI, we investigate a large-scale ejective solar eruption of 2014 December 18 from…
Magnetic Flux Cancelation as the Origin of Solar Quiet Region Pre-Jet Minifilaments
Navdeep K. Panesar, Alphonse C. Sterling, Ronald L. Moore
We investigate the origin of ten solar quiet region pre-jet minifilaments, using EUV images from SDO/AIA and magnetograms from SDO/HMI. We recently found panesar16b that quiet regi…
New Evidence that Magnetoconvection Drives Solar-Stellar Coronal Heating
Sanjiv K. Tiwari, Julia K. Thalmann, Navdeep K. Panesar +2
How magnetic energy is injected and released in the solar corona, keeping it heated to several million degrees, remains elusive. Coronal heating generally increases with increasing…
Small-scale filament eruptions as the driver of solar coronal hole X-ray jets
Alphonse C. Sterling, Ronald L. Moore, David A. Falconer +1
Solar X-ray jets are evidently made by a burst of reconnection of closed magnetic field in a jet's base with ambient "open" field (1,2). In the widely-accepted version of the "emer…
Solar Active Region Coronal Jets II: Triggering and Evolution of Violent Jets
Alphonse C. Sterling, Ronald L. Moore, David A. Falconer +2
We study a series of X-ray-bright, rapidly-evolving active-region coronal jets outside the leading sunspot of AR 12259, using Hinode/XRT, SDO/AIA and HMI, and IRIS data. The detail…
