Heating of beam ions by ion acoustic waves
Satellite measurements show that ion beams above the auroral acceleration region are heated to hundreds of eV in a direction perpendicular to the magnetic ®eld. We show that ion acoustic waves may be responsible for much of this heating. Even in the absence of a positive slope in the velocity distribution of the beam ions, ion acoustic waves can be generated by a fan instability. We present ana...
متن کاملOn Heating of Solar Corona and Acceleration of Low-Speed Solar Wind by Acoustic Waves Generated in Corona
We investigate possibilities of solar coronal heating by acoustic waves generated not at the photosphere but in the corona, aiming at heating in the midto low-latitude corona where the low-speed wind is expected to come from. Acoustic waves of period τ ∼ 100s are triggered by chromospheric reconnection, one model of small scale magnetic reconnection events recently proposed by Sturrock. These w...
متن کاملThe Heating of the Solar Chromosphere and Corona by Non-stationary Acoustic Waves
The heating of the solar chromosphere and corona is a fundamental problem that still deserves further investigation. Recent improvement of the theory of acoustic wave propagation in the solar atmosphere including non-stationary solutions, carried out by Wang et al. (1994), raises the possibility for a rediscussion about the role of these waves as a heating mechanism. The main result of this the...

متن کاملThe effects of high-frequency Alfvén waves on coronal heating and solar wind acceleration
Wave effects in a two-fluidmodel for the solar corona and wind are studied. Heating and acceleration are achieved by high-frequency Alfvén waves, which are assumed to be created through small-scale reconnections in the chromospheric network. The wave energy flux Fw is given in the model as a lower boundary condition. Waves with a power spectrum of the form P0(f/f0)−1 in the frequency range from...
