  • Coronal heating by magnetohydrodynamic turbulence driven by reflected low-frequency waves

    Matthaeus, William H.; Zank, Gary P.; Oughton, Sean; Mullan, D. J.; Dmitruk, Pablo (IOP PUBLISHING LTD, 1999)
    A candidate mechanism for the heating of the solar corona in open field line regions is described. The interaction of Alfvén waves, generated in the photosphere or chromosphere, with their reflections and the subsequent ...
  • Coronal heating distribution due to low-frequency, wave-driven turbulence

    Dmitruk, Pablo; Matthaeus, William H.; Milano, L. J.; Oughton, Sean; Zank, Gary P.; Mullan, D. J. (University of Chicago Press, 2002)
    The heating of the lower solar corona is examined using numerical simulations and theoretical models of magnetohydrodynamic turbulence in open magnetic regions. A turbulent energy cascade to small length scales perpendicular ...
  • Heating of the low-latitude solar wind by dissipation of turbulent magnetic fluctuations

    Smith, Charles W.; Matthaeus, William H.; Zank, Gary P.; Ness, Norman F.; Oughton, Sean; Richardson, John D. (American Geophysical Union (AGU), 2001-05)
    We test a theory presented previously to account for the turbulent transport of magnetic fluctuation energy in the solar wind and the related dissipation and heating of the ambient ion population. This theory accounts for ...
  • Heating the outer heliosphere by pickup protons

    Smith, Charles W.; Isenberg, Philip A.; Matthaeus, William H.; Richardson, John D.; Oughton, Sean; Zank, Gary P. (American Institute of Physics, 2004)
    There is a growing body of literature that demonstrates the ability of a turbulent cascade within the solar wind to heat the thermal protons. Several sources of energy are required to accomplish the observed heating. Wind ...
  • Mass-loading and parallel magnetized shocks

    Zank, Gary P.; Oughton, Sean; Neubauer, F. M.; Webb, G. M. (1991)
    Recent observations at comets Giacobini-Zinner and Halley suggest that simple non-reacting gas dynamics or MHD is an inappropriate description for the bow shock. The thickness of the observed (sub)shock implies that ...
