On the Magnetic Flux Budget in Low-Corona Magnetic Reconnection and Interplanetary Coronal Mass Ejections (2007, background): “In the first picture, magnetic flux ropes emerge frombelow the Sun’s surface (Low1994; Chen 1989; Fan & Gibson 2004).”
Magnetic flux emergence in granular convection: radiative MHD simulations and observational signatures (2007, background): “…studies in the literature has been on the evolution of the emerging magnetic field in the corona (Fan, 2001; Magara, 2001; Magara & Longcope, 2003; Fan & Gibson, 2004; Abbett & Fisher, 2003; Archontis et al., 2004, 2005; Török & Kliem, 2005; Isobe et al., 2005; Galsgaard et al., 2005; Leake &…”
Coronal Mass Ejections as Loss of Confinement of Kinked Magnetic Flux Ropes (2005, methodology): “The nonlinear kink evolution leads to the formation of an intense current layer that displays an inverse-S (forward-S) shape for a left-hand-twisted (right-hand-twisted) flux tube, consistent with the observed X-ray sigmoid morphology (Fan & Gibson 2004; Gibson et al. 2004).”
Solar Force-free Magnetic Fields (2012, methodology): “(2007) applied the method to the same flux-rope simulation by Fan and Gibson (2004) as discussed in the examples above, and the method recovered about a fraction of 0.”
MAGNETIC FIELD STRUCTURES TRIGGERING SOLAR FLARES AND CORONAL MASS EJECTIONS (2012, methodology): “Although this model corresponds to the kinematic model of emerging flux (Fan & Gibson 2004), we adopt it as a way to dynamically form a variety of magnetic structures rather than as the model of flux emerging.”
The Three-dimensional Interaction between Emerging Magnetic Flux and a Large-Scale Coronal Field: Reconnection, Current Sheets, and Jets (2005, background): “Fan & Gibson (2004) considered the interaction between a preexisting coronal arcade and magnetic flux that is injected in the corona via a combination of an inflow and an electric field at the lower boundary of the integration box.”
OBSERVING FLUX ROPE FORMATION DURING THE IMPULSIVE PHASE OF A SOLAR ERUPTION (2011, background): “Considerable efforts have also been made in numerical MHD simulations to study the formation and dynamic behavior of flux ropes (Amari et al. 2000, 2003; Aulanier et al. 2010; Fan & Gibson 2003, 2004).”
An Overview of Existing Algorithms for Resolving the 180° Ambiguity in Vector Magnetic Fields: Quantitative Tests with Synthetic Data (2006, methodology): “Case #1: Twisted Fluxrope in a Potential-Field Arcade, µ = 1.0 The first test case is a “photospheric” vector magnetogram constructed from the MHD model of Fan and Gibson (Fan and Gibson (2003); Fan and Gibson (2004)), paper.tex; 25/05/2006; 9:44; p.15 provided courtesy of Y. Fan.”
Coronal prominence structure and dynamics: A magnetic flux rope interpretation (2006, background): “We have previously demonstrated that current sheets do in fact form along this sigmoid-shaped surface in our simulations, both during eruption [ Fan and Gibson, 2004; Gibson et al., 2004; Fan, 2005], and in the quiescent, noneruptive flux rope equilibrium being discussed in this paper [Fan and Gibs”
Confined and Ejective Eruptions of Kink-unstable Flux Ropes (2005, background): “They have shown that this model relaxes to a numerical equilibrium very close to the analytical expressions in the case of subcritical twist and that the helical kink instability develops for supercritical twist (see also Fan & Gibson 2003, 2004).”
Nonlinear Force-free Field Modeling of a Solar Active Region around the Time of a Major Flare and Coronal Mass Ejection (2007, background): “Then there are ‘‘twisted’’ flux ropes that may either emerge as such (e.g., Fan & Gibson 2004; Amari et al. 2004) or form from photospheric vortical motions (e.g., Amari et al. 1996; Török & Kliem 2003; Aulanier et al. 2005).”
The Calm before the Storm: The Link between Quiescent Cavities and Coronal Mass Ejections (2006, background): “…rising and swelling of a cavity prior to its eruption discussed in x 4.3.1 is consistent with the progression of a flux rope through a sequence of quasi-static equilibria as it emerges from beneath the photosphere and rises into the corona (Wolfson et al. 1987; Fan & Gibson 2004, 2005; Fan 2006).”
The Physical Processes of CME/ICME Evolution (2017, methodology): “Starting from analytical flux-rope models, Fan and Gibson (2004) and Török and Kliem (2005) reported similarly large rotations (up to 120°) as a result of the same instability.”
The Partial Expulsion of a Magnetic Flux Rope (2006, background): “…a pre-CME flux rope (Wolfson et al. 1987; Low & Hundhausen 1995; Linker et al. 2003; Gibson et al. 2006), as are transient sigmoid brightenings (Rust & Kumar 1996; Fan & Gibson 2003, 2004; Kliem et al. 2004) and their transition to cusped postflare loops (Amari et al. 2003b; To¨rök & Kliem 2005).”
Coronal Mass Ejections: Observations (2012, background): “, 2008), involve runaway magnetic reconnection between the erupting core and the strapping field, while others, such as the kink instability (e.g., Török and Kleim, 2003, 2005; Fan and Gibson, 2004) involve the twisting of the core field.”
