Eruption of magnetic flux ropes during flux emergence (2008, unknown): “They can occur throughout the lifetime of an active region, from its emergence to its decay (e.g. Green et al. 2002).”
The solar magnetic field (2006, background): “An active region was continuously observed and its helicity budget monitored for five solar rotations [509].”
Photospheric flux density of magnetic helicity (2005, background): “The flux of magnetic helicity from differential motion is usually found to be too small (typically a factor 10) to explain the helicity ejected in CMEs Appendix A is only available in electronic form at http://www.edpsciences.org (Démoulin et al. 2002; Green et al. 2002; Nindos et al. 2003).”
The Partial Expulsion of a Magnetic Flux Rope (2006, background): “…flux emergence (Tanaka 1991; Lites et al. 1995; Leka et al. 1996), apparent shear or rotational motions at the photosphere (López Fuentes 2000; Green et al. 2002; Gibson et al. 2004), filaments (Priest et al. 1989; Rust 1994; Aulanier & De´moulin 1998; Amari et al. 1999; van Ballegooijen…”
Magnetic Energy and Helicity Fluxes at the Photospheric Level (2003, background): “This implies a correction factor slightly above 2 to the helicity fluxes computed by Chae (2001), Chae et al. (2001), Démoulin et al. (2002), Green et al. (2002), Kusano et al. (2002), Moon et al. (2002a,2002b), Nindos & Zhang (2002).”
CRITERIA FOR FLUX ROPE ERUPTION: NON-EQUILIBRIUM VERSUS TORUS INSTABILITY (2010, background): “…of new emerging magnetic flux, progressive dispersion of the whole flux, the build up of a very sheared field in the vicinity of the photospheric inversion line (PIL), and the cancelation of flux at the PIL (e.g. van Driel-Gesztelyi 1998; Green et al. 2002; van Driel-Gesztelyi et al. 2003).”
The Magnetic Helicity Budget of Solar Active Regions and Coronal Mass Ejections (2003, background): “of vertical flux does not necessarily mean that there is no contribution of emerging flux to the helicity injected into the corona (Démoulin et al. 2002b; Green et al. 2002).”
The Calm before the Storm: The Link between Quiescent Cavities and Coronal Mass Ejections (2006, background): “…emerging twisted flux (Tanaka 1991; Leka et al. 1996; Lites et al. 1995), apparent shear/rotational motions at the photosphere (Lopez Fuentes 2000; Green et al. 2002; Mandrini et al. 2005; Gibson et al. 2004), observed properties of coronal prominences (Priest et al. 1989; Rust 1994; Rust & Kumar…”
Interplanetary flux rope ejected from an X-ray bright point. The smallest magnetic cloud source-region ever observed (2005, methodology): “First, we compute the coronal field assuming a given value for α, then we compare the computed field lines to the observed TRACE coronal loops and, finally, through successive steps we select the value of α that gives the best global fit (Green et al. 2002).”
