Lopés Fuentes et al, 2008 Countered DeForest’s argument Claimed that their method could distinguish between unresolved expanding and not expanding but resolved strands Conversation switched to theories that predict constant cross-section loops (i.e. Constant B).
How Could Loops be of Constant Cross-Section? Twist? (Klimchuk et al., 2000) Separators? (Plowman et al., 2009)
How Could Loops be of Constant Cross-Section? Emission loops (eLoops) do not actually trace field lines (Peter & Bingert, 2012)
Summary Loop geometry has an effect on fundamental loop properties such as temperature and density (pressure) Vesecky, Antiochos, and Underwood, 1979; Mariska, 1984; Schrijver, Lemen and Mewe, 1989; Dowdy, Emslie, and Moore, 1987 Modeled near-resolution, expanding loops can appear to be of constant cross-section just like those “pesky” observations Loops must be many pixels wide to make width determinations Is it safe to use magnetic fields to generate loop geometries for 1D models?
