    • Amplitudes and energy fluxes of simulated decayless kink oscillations 

      Karampelas, Konstantinos; Van Doorsselaere, Tom; Pascoe, David J.; Guo, Mingzhe; Antolin, Patrick (2019-05-21) - Journal article
      Recent observations with the Atmospheric Imaging Assembly (AIA) instrument on the SDO spacecraft have revealed the existence of decayless coronal kink oscillations. These transverse oscillations are not connected to any ...
    • Apparent cross-field superslow propagation of magnetohydrodynamic waves in solar plasmas 

      Kaneko, T; Goossens, Marcel; Soler, Roberto; Terradas, Jaume; Van Doorsselaere, Tom; Yokoyama, T; Wright, Andrew Nicholas (2015-10-15) - Journal article
      In this paper we show that the phase mixing of continuum Alfvén waves and/or continuum slow waves in magnetic structures of the solar atmosphere as, e.g., coronal arcades, can create the illusion of wave propagation across ...
    • Broadening of the differential emission measure by multi-shelled and turbulent loops 

      Van Doorsselaere, Tom; Antolin, Patrick; Karampelas, Kostas (2018-12) - Journal article
      Context. Broad differential emission measure (DEM) distributions in the corona are a sign of multi-thermal plasma along the line-of-sight.Traditionally, this is interpreted as evidence of multi-stranded loops. Recently, ...
    • Forward modeling of EUV and gyrosynchrotron emission from coronal plasmas with FoMo 

      Van Doorsselaere, Tom; Antolin, Patrick; Yuan, Ding; Reznikova, Veronika; Magyar, Norbert (2016-02-26) - Journal article
      The FOMO code was developed to calculate the EUV and UV emission from optically thin coronal plasmas. The input data for FOMO consists of the plasma density, temperature and velocity on a 3D grid. This is translated to ...
    • Heating effects from driven transverse and Alfvén waves in coronal loops 

      Guo, Mingzhe; Van Doorsselaere, Tom; Karampelas, Kostas; Li, Bo; Antolin, Patrick; De Moortel, Ineke (2019-01-10) - Journal article
      Recent numerical studies revealed that transverse motions of coronal loops can induce the Kelvin-Helmholtz Instability (KHI). This process could be important in coronal heating because it leads to dissipation of energy at ...
    • Influence of resonant absorption on the generation of the Kelvin-Helmholtz instability 

      Antolin, Patrick; Van Doorsselaere, Tom (2019-06-04) - Journal article
      The inhomogeneous solar corona is continuously disturbed by transverse MHD waves. In the inhomogeneous environment of coronal flux tubes, these waves are subject to resonant absorption, a physical mechanism of mode conversion ...
    • The influence of the magnetic field on running penumbral waves in the solar chromosphere 

      Jess, David; Reznikova, V; Van Doorsselaere, Tom; Mackay, Duncan Hendry; Keys, Peter (2013-12-03) - Journal article
      We use images of high spatial and temporal resolution, obtained using both ground- and space-based instrumentation, to investigate the role magnetic field inclination angles play in the propagation characteristics of running ...
    • Resonant absorption of transverse oscillations and associated heating in a solar prominence. I. Observational aspects 

      Okamoto, Takenori J.; Antolin, Patrick; De Pontieu, Bart; Uitenbroek, Han; Van Doorsselaere, Tom; Yokoyama, Takaaki (2015-08-11) - Journal article
      Transverse magnetohydrodynamic waves have been shown to be ubiquitous in the solar atmosphere and can, in principle, carry sufficient energy to generate and maintain the Sun's million-degree outer atmosphere or corona. ...
