Coronal Heating versus Solar Wind Acceleration

Parker’s initial insights from 1958 provided a key causal link between the heating of the solar corona and the acceleration of the solar wind. However, we still do not know what fraction of the solar wind’s mass, momentum, and energy flux is driven by Parker-type gas pressure gradients, and what fraction is driven by, e.g., wave-particle interactions or turbulence. SOHO has been pivotal in brin...

Heating and acceleration of minor ions in the solar wind

We make use of the results of a one-ion model of McKenzie et al. (1997) to obtain the critical solution describing the acceleration of a two-ion solar wind. The model includes preferential heating of the heavy ion species and the temperature anisotropy expected if the heating is predominantly due to ioncyclotron damping. The relationship of the model to the picture emerging from UVCS/SOHO obser...

Heating of the solar wind with electron and proton effects

We examine the effects of including effects of both protons and electrons on the heating of the fast solar wind through two different approaches. In the first approach, we incorporate the electron temperature in an MHD turbulence transport model for the solar wind. In the second approach, we adopt more empirically based methods by analyzing the measured proton and electron temperatures to calcu...

Turbulent Heating in the Solar Wind and in the Solar Corona

In this paper we calculate the turbulent heating rates in the solar wind using the Kolmogorov-like MHD turbulence phenomenology with Kolmogorov’s constants calculated by Verma and Bhattacharjee [1995b,c]. We find that the turbulent heating can not account for the total heating of the nonAlfvénic streams in the solar wind. We show that dissipation due to thermal conduction is also a potential he...

Heating of the Solar Wind Beyond 1 AUby

The deposition of energy into the solar wind beyond 1 AU is thought to result from the dissipation of low frequency magnetohydrodynamic (MHD) turbulence via kinetic processes at spatial scales comparable to the ion gyroradius. Beyond 1 AU, solar wind turbulence is comprised of both a decaying component generated in the corona and turbulence generated dynamically in situ by processes such as str...
