Further Evidence for the Minifilament-Eruption Scenario for Solar Polar Coronal Jets
Tomi K. Baikie, Alphonse C. Sterling, Ronald L. Moore +4
We examine a sampling of 23 polar-coronal-hole jets. We first identified the jets in soft X-ray (SXR) images from the X-ray telescope (XRT) on the Hinode spacecraft, over 2014-2016…
Toward Improved Understanding of Magnetic Fields Participating in Solar Flares: Statistical Analysis of Magnetic Field within Flare Ribbons
Maria D. Kazachenko, Benjamin J. Lynch, Antonia Savcheva +2
Violent solar flares and coronal mass ejections (CMEs) are magnetic phenomena. However, how magnetic fields reconnecting in the flare differ from non-flaring magnetic fields remain…
Laboratory study of the torus instability threshold in solar-relevant, line-tied magnetic flux ropes
Andrew Alt, Clayton E. Myers, Hantao Ji +7
Coronal mass ejections (CME) occur when long-lived magnetic flux ropes (MFR) anchored to the solar surface destabilize and erupt away from the Sun. This destabilization is often de…
Understanding the plasma and magnetic field evolution of a filament using observations and Nonlinear force-free field modelling
Stephanie L. Yardley, Antonia Savcheva, Lucie M. Green +4
We present observations and magnetic field models of an intermediate filament present on the Sun in August 2012, associated with a polarity inversion line that extends from AR 1154…
Data-Optimized Coronal Field Model: I. Proof of Concept
K. Dalmasse, A. Savcheva, S. E. Gibson +5
Deriving the strength and direction of the three-dimensional (3D) magnetic field in the solar atmosphere is fundamental for understanding its dynamics. Volume information on the ma…
Coiling and Squeezing: Properties of the Local Transverse Deviations of Magnetic Field Lines
Svetlin Tassev, Antonia Savcheva
We study the properties of the local transverse deviations of magnetic field lines at a fixed moment in time. Those deviations "evolve" smoothly in a plane normal to the field-line…
