  • Coronal Heating by MHD Waves 
    Van Doorsselaere, Tom; Srivastava, Abhishek; Antolin, Patrick; Magyar, Norbert; Vasheghani Farahani, Soheil; Tian, Hui; Kolotkov, Dmitrii; Ofman, Leon; Guo, Mingzhe; Arregui, Iñigo; de Moortel, Ineke; Pascoe, David D. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    The heating of the solar chromosphere and corona to the observed high temperatures, imply the presence of ongoing heating that balances the strong radiative and thermal conduction losses expected in the solar atmosphere. ...
  • Investigating coronal wave energy estimates using synthetic non-thermal line widths 
    Fyfe, Lyanne E.; Howson, Thomas A.; de Moortel, Ineke; Pant, Vaibhav; Van Doorsselaere, Tom (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Aims. Estimates of coronal wave energy remain uncertain as a large fraction of the energy is likely hidden in the non-thermal line widths of emission lines. In order to estimate these wave energies, many previous studies ...
  • Magnetoacoustic wave energy dissipation in the atmosphere of solar pores 
    Gilchrist-Millar, Caitlin A.; Jess, David B.; Grant, Samuel D. T.; Keys, Peter H.; Beck, Christian; Jafarzadeh, Shahin; Riedl, Julia M.; Van Doorsselaere, Tom; Ruiz Cobo, Basilio (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    The suitability of solar pores as magnetic wave guides has been a key topic of discussion in recent years. Here, we present observational evidence of propagating magnetohydrodynamic wave activity in a group of five ...
  • Magnetohydrodynamic Waves in Open Coronal Structures 
    Banerjee, D.; Prasad, S. Krishna; Pant, V.; McLaughlin, J. A.; Antolin, Patrick; Magyar, Norbert; Ofman, Leon; Tian, H.; Van Doorsselaere, Tom; de Moortel, Ineke; Wang, T. J. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)
    Modern observatories have revealed the ubiquitous presence of magnetohydrodynamic waves in the solar corona. The propagating waves (in contrast to the standing waves) are usually originated in the lower solar atmosphere ...
  • Probing the Physics of the Solar Atmosphere with the Multi-slit Solar Explorer (MUSE). I. Coronal Heating 
    De Pontieu, Bart Walter; Testa, Paola; Martinez-Sykora, Juan; Antolin, Patrick; Karampelas, Konstantinos; Hansteen, Viggo Haraldson; Rempel, Matthias; Cheung, Mark C. M.; Reale, Fabio; Danilovic, Sanja; Pagano, Paolo; Polito, Vanessa; de Moortel, Ineke; Nóbrega Siverio, Daniel Elias; Van Doorsselaere, Tom; Petralia, Antonino; Asgari-Targhi, Mahboubeh; Boerner, Paul; Carlsson, Mats; Chintzoglou, Georgios; Daw, Adrian; DeLuca, Edward; Golub, Leon; Matsumoto, Takuma; Ugarte-Urra, Ignacio; McIntosh, Scott W. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
  • Resonant absorption in expanding coronal magnetic flux tubes with uniform density 
    Howson, T. A.; de Moortel, Ineke; Antolin, Patrick; Van Doorsselaere, Tom; Wright, A. N. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Aims. We investigate the transfer of energy between a fundamental standing kink mode and azimuthal Alfvén waves within an expanding coronal magnetic flux tube. We consider the process of resonant absorption in a loop with ...
  • RESONANT ABSORPTION OF TRANSVERSE OSCILLATIONS AND ASSOCIATED HEATING IN A SOLAR PROMINENCE. I. OBSERVATIONAL ASPECTS 
    Okamoto, T. J.; Antolin, Patrick; De Pontieu, Bart Walter; Uitenbroek, Han; Van Doorsselaere, Tom; Yokoyama, T (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    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. ...
