  • Dynamical age of solar wind turbulence in the outer heliosphere

    Matthaeus, William H.; Smith, Charles W.; Oughton, Sean (American Geophysical Union (AGU), 1998)
    In an evolving turbulent medium, a natural timescale can be defined in terms of the energy decay time. The time evolution may be complicated by other effects such as energy supply due to driving, and spatial inhomogeneity. ...
  • 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 ...
  • MHD‐driven kinetic dissipation in the solar wind and corona

    Leamon, R. J.; Matthaeus, William H.; Smith, Charles W.; Zank, Gary P.; Mullan, D. J.; Oughton, Sean (University of Chicago Press, 2000)
    Mechanisms for the deposition of heat in the lower coronal plasma are discussed, emphasizing recent attempts to reconcile the fluid and kinetic perspectives. Structures at magnetohydrodynamic (MHD) scales may drive a ...
  • Solar wind turbulent heating by interstellar pickup protons: 2-component model

    Isenberg, Philip A.; Oughton, Sean; Smith, Charles W.; Matthaeus, William H. (American Institute of Physics, 2010)
    We apply a recently developed 2-component phenomenology to the turbulent heating of the core solar wind protons as seen at the Voyager 2 spacecraft. We find that this new description improves the model predictions of core ...
