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

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

Origins of the Ambient Solar Wind: Implications for Space Weather
Space Science Reviews, 2017The Sun’s outer atmosphere is heated to temperatures of millions of degrees, and solar plasma flows out into interplanetary space at supersonic speeds. This paper reviews our current understanding of these interrelated problems: coronal heating and the ...

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 ...

Interdependence of solar wind models and solar wind observations
AIP Conference Proceedings, 1997A brief overview of the observations in the inner corona is presented together with three different solar wind models. It is shown that the very high flow speeds derived from the observations in the inner corona can be modeled if either the proton temperature is extremely high, or if there exists a mechanism that adds momentum to the flow much closer ...

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.

Space Science Reviews, 1983
Some advances in the hydrodynamical large-scale theory, on the one hand, and in the kinetic theory, on the other hand, of the solar wind are reviewed. For brevity, we sketch the general frame, point out the problems and approaches and then illustrate by a few examples the ways in which progress has been achieved during the past four years.
