The current status of our understanding of the nature and origin of the solar wind is briefly reviewed, with emphasis being placed on the need for wave-particle interactions to account for the main energy source as well as details of the particle distribution functions.

>Hydrodynamic expansion of the solar corona is the basis for solar corpuscular radiation. The quiet day coronal temperatures of 1 to 2 x 10/sup 6/ deg K yield a solar wind of several hundred km/sec and a density of 5 to 50 particles/cm/sup 3/ at the orbit of Earth.

ACCELERATION OF THE SOLAR WIND
Space Science Reviews, 1982In this review, we discuss critically recent research on the acceleration of the solar wind, giving emphasis to high-speed solar wind streams emanating from solar coronal holes. We first explain why thermally driven wind models constrained by solar and interplanetary observations encounter substantial difficulties in explaining high speed streams. Then,

AIP Conference Proceedings, 2007
We discuss the energy balance of the upper solar atmosphere and the solar wind, showing how the properties of the corona and solar wind are influenced by the three energy loss mechanisms available to the solar atmosphere; the solar wind, heat conduction, and radiation. We show that the Sun must have a corona with temperature of order 106 K irrespective

Turbulence in the Solar Atmosphere and Solar Wind
Space Science Reviews, 2010The objective of this review article is to critically analyze turbulence and its role in the solar atmosphere and solar wind, as well as to provide a tutorial overview of topics worth clarification. Although turbulence is a ubiquitous phenomenon in the sun and its heliosphere, many open questions exist concerning the physical mechanisms of turbulence ...

Solar and solar-wind isotopic compositions
Earth and Planetary Science Letters, 2004With only a few exceptions, the solar photosphere is thought to have retained the mean isotopic composition of the original solar nebula, so that, with some corrections, the photosphere provides a baseline for comparison of all other planetary materials. There are two sources of information on the photospheric isotopic composition: optical observations,

This chapter is intended to be an overview of the aspects of solar wind, with particular emphasis on the properties of the solar wind within about 1AU of the Sun. The topic is split into two parts on the basis of two types of solar wind flows, (i) quasi-stationary winds and (ii) transient flows.

Shortly before the beginning of the space age, Eugene N. Parker of the University of Chicago predicted that interplanetary space would be filled with a plasma flowing rapidly outward from the Sun (Parker 1958). The likelihood that the Sun ejects charged particles that cause auroral and magnetic activity on Earth was generally accepted by that time. The

The Sun continually ejects matter into space, blowing a huge bubble of supersonic plasma. This solar wind bathes the whole solar system and shapes all planetary environments. The growth of space technology has considerably increased our knowledge of this medium.

Reports on Progress in Physics, 1967
The historical evidence that the Sun is a constant source of an outwardflowing supersonic stream of ionized hydrogen and helium now called the solar wind has been confirmed by many recent satellite measurements. Although the intensity of the wind varies and increases greatly as a result of sunspot activity on the solar surface, normally during quiet ...
