Formation of an observed eruptive flux rope above the torus instability threshold through tether-cutting magnetic reconnection
Avijeet Prasad, Sanjay Kumar, Alphonse C. Sterling +4
Erupting magnetic flux ropes (MFRs) play a crucial role in producing solar flares. However, the formation of erupting MFRs in complex coronal magnetic configurations and their subs…
Prospective Implications of EUV Coronal Plumes for Magnetic-network Genesis of Coronal Heating, Coronal-hole Solar Wind, and Solar-wind Magnetic-field Switchbacks
Ronald L. Moore, Sanjiv K. Tiwari, Navdeep K. Panesar +1
We propose that coronal heating in EUV coronal plumes is weaker, not stronger, than in adjacent non-plume coronal magnetic funnels. This expectation stems from (i) the observation…
Future High-Resolution and High-Cadence Observations for Unraveling Small-Scale Explosive Solar Features
Alphonse C. Sterling, Ronald L. Moore, Navdeep K. Panesar +3
Solar coronal jets are frequently occurring collimated ejections of solar plasma, originating from magnetically mixed polarity locations on the Sun of size scale comparable to that…
Inconspicuous Solar Polar Coronal X-ray Jets as the Source of Conspicuous Hinode/EUV Imaging Spectrometer (EIS) Doppler Outflows
Alphonse C. Sterling, Conrad Schwanitz, Louise K. Harra +3
We examine in greater detail five events previously identified as being sources of strong transient coronal outflows in a solar polar region in Hinode/EUV Imaging Spectrometer (EIS…
Homologous compact major blowout-eruption solar flares and their production of broad CMEs
Suraj Sahu, Bhuwan Joshi, Alphonse C. Sterling +2
We analyze the formation mechanism of three homologous broad coronal mass ejections (CMEs) resulting from a series of solar blowout-eruption flares with successively increasing int…
Another Look at Erupting Minifilaments at the Base of Solar X-Ray Polar Coronal "Standard" and "Blowout" Jets
Alphonse C. Sterling, Ronald L. Moore, Navdeep K. Panesar
We examine 21 solar polar coronal jets that we identify in soft X-ray images obtained from the Hinode/X-ray telescope (XRT). We identify 11 of these jets as blowout jets and four a…
