MHD seismology of coronal loops using the period and damping of quasi-mode kink oscillations (2007, background): “Several mechanisms are currently under study, such as non-ideal effects; lateral wave leakage due to the curvature of the loops (Roberts 2000); mechanisms based on the topology of magnetic field lines (Schrijver & Brown 2000); foot-point leakage through the chromospheric density gradient (De…”
Impulsive Phase Flare Energy Transport by Large-Scale Alfvén Waves and the Electron Acceleration Problem (2007, background): “In a corona with strong nonuniformities perpendicular to the field, the damping of Alfvén waves is by phase mixing (e.g., Roberts 2000).”
Self-consistent Coronal Heating and Solar Wind Acceleration from Anisotropic Magnetohydrodynamic Turbulence (2007, background): “…extensively in the context of the dense coronal base (e.g., Alfvén 1947; Kuperus et al. 1981; Narain & Ulmschneider 1990, 1996; Porter et al. 1994; Roberts 2000), but the open field lines that feed the solar wind have lower densities and are thus less collisionally dominated than closed loops in…”
Transverse Oscillations of Coronal Loops (2009, background): “A few different mechanisms of damping were suggested (e.g. Roberts (2000)).”
Characteristics of transverse oscillations in a coronal loop arcade (2004, background): “The damping time in this case is equal to (Roberts, 2000) τ = ( 6L2 νπ2V ′2 A j 2 )1/3 , (5) where ν is the coronal, kinematic, shear viscosity coefficient.”
On the Generation, Propagation, and Reflection of Alfvén Waves from the Solar Photosphere to the Distant Heliosphere (2004, background): “…MBP fluctuations, there is ambient acoustic wave energy excited by convection, shock steepening in the chromosphere and transition region, and both driven and free oscillations in sunspots and coronal loops (see recent reviews by Axford et al. 1999; Roberts 2000; Bogdan 2000; Hirzberger 2003).”
Vertical oscillations of a coronal loop observed by TRACE (2004, methodology): “The observations of such oscillations and waves are leading to a diagnostic tool, dubbed coronal seismology, for determining unknown coronal parameters, such as the magnetic field in coronal loops (e.g. Roberts 2000; Nakariakov & Ofman 2001).”
Alfvén Waves in the Solar Atmosphere (2012, background): “The second class predicts that the heating is driven by magnetohydrodynamic (MHD) waves (Alfvén 1947; Osterbrock 1961; Ionson 1978; Hollweg 1991), most likely propagating from the lower atmosphere (Roberts 2000).”
Alfvénic Turbulence in the Extended Solar Corona: Kinetic Effects and Proton Heating (2003, background): “The precise generation mechanisms of the lowfrequency waves at the solar surface are unimportant in the context of this paper (see, e.g., Roberts 2000).”
Hot coronal loop oscillations observed with SUMER: Examples and statistics (2003, background): “Various periodic and quasiperiodic oscillations in radio, visible, EUV, and soft X-ray (SXR) radiation have been observed for decades (e.g. reviews by Aschwanden 1987; 2002; Roberts 2000).”
Coronal Waves and Oscillations (2005, background): “Another alternative interpretation is connected with the effect of phase-mixing (Roberts, 2000; Ofman and Aschwanden, 2002) (see Section 2.”
Line-of-sight effects on observability of kink and sausage modes in coronal structures with imaging telescopes (2002, unknown): “In addition, Alfvén waves, which are linearly incompressible, as well as almost incompressible kink modes of coronal magnetic structures (e.g., Roberts 2000 and references therein), can also be detected with an imaging telescope with sufficient spatial and temporal resolution, if perturbations of…”
Coronal loop oscillations - An interpretation in terms of resonant absorption of quasi-mode kink oscillations (2002, background): “…support for the assumption that both L and w are proportional to l. Application of the theoretical expression for the decay time, as it is derived by Roberts (2000) from the Heyvaerts & Priest (1983) analysis, to the observed values leads to values of the Reynolds numbers for the oscillating…”
Determination of the Coronal Density Stratification from the Observation of Harmonic Coronal Loop Oscillations (2005, background): “Several wave types have been identified, and they are all believed to carry valuable information about the plasma through which they propagate, opening up the possibility of coronal seismology (Uchida 1970; for reviews, see Roberts 2000; Aschwanden 2004).”
Hinode observations of transverse waves with flows in coronal loops (2008, background): “There are three main classes of wave damping mechanism that are currently debated in the literature (e.g., Roberts 2000; Ruderman & Roberts 2002; Ofman 2002; Ofman & Aschwanden 2002; Goossens et al. 2002; Van Doorsselaere et al. 2004; Aschwanden 2005): leakage, resonant absorption or mode…”
The Damping of Coronal Loop Oscillations (2002, background): “An understanding of coronal oscillations is especially important because such oscillations may shed light on the puzzle of coronal heating, and, furthermore, they may provide seismic information about the coronal plasma (see, e.g., Roberts 2000).”
