Coronal loop seismology using multiple transverse loop oscillation harmonics (2007, background): “…mechanisms were treated improperly, e.g. resonant absorption by assuming that the length and width of the loop are proportional to the inhomogeneity scale, (Goossens et al. 2002) and the large error bars on the observations do not currently allow to distinguish between several damping mechanisms.”

Characteristics of transverse oscillations in a coronal loop arcade (2004, background): “Goossens, Andries, and Aschwanden (2002) argued that the quick decay of the kink oscillations could still be explained in terms of resonant absorption, provided the ratio of the inhomogeneity length scale to the radius of the loop is allowed to vary from loop to loop.”
Effect of longitudinal magnetic and density inhomogeneity on transversal coronal loop oscillations (2008, background): “…from the work of Hollweg & Yang (1988), it has been shown that varying plasma density in the radial direction results in a change of period and damping of MHD waves (see e.g., Ruderman & Roberts 2002; Goossens et al. 2002; Aschwanden et al. 2003; Van Doorsselaere et al. 2004; Arregui et al. 2007).”
