Using Coronal Loops to Reconstruct the Magnetic Field of an Active Region Before and After a Major Flare
A. Malanushenko, C. Schrijver, M. L. DeRosa +1
The shapes of solar coronal loops are sensitive to the presence of electrical currents that are the carriers of the nonpotential energy available for impulsive activity. We use thi…
Heating and Dynamics of Two Flare Loop Systems Observed by AIA and EIS
Y. Li, J. Qiu, M. D. Ding
We investigate heating and evolution of flare loops in a C4.7 two-ribbon flare on 2011 February 13. From SDO/AIA imaging observations, we can identify two sets of loops. Hinode/EIS…
Calibrating Data from the Hinode/X-Ray Telescope and Associated Uncertainties
Adam R. Kobelski, Steven H. Saar, Mark A. Weber +2
The X-Ray Telescope (XRT) onboard the Hinode satellite, launched 23 September 2006 by the Japanese Aerospace Exploration Agency (JAXA) is a joint mission between Japan, the United…
Breakout and Tether-cutting Eruption Models Are Both Catastrophic (Sometimes)
D. W. Longcope, T. G. Forbes
We present a simplified analytic model of a quadrupolar magnetic field and flux rope to model coronal mass ejections. The model magnetic field is two-dimensional, force-free and ha…
Approximate black hole binary spacetime via asymptotic matching
Bruno C. Mundim, Hiroyuki Nakano, Nicolás Yunes +3
We construct a fully analytic, general relativistic, nonspinning black hole binary spacetime that approximately solves the vacuum Einstein equations everywhere in space and time fo…
Constraining the Origin of Magnetar Flares
Bennett Link
Sudden relaxation of the magnetic field in the core of a magnetar produces mechanical energy primarily in the form of shear waves which propagate to the surface and enter the magne…
