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,

Solar Physics, 1985
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.

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.

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 ...

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 ...

>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.

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.

The first evidence of the solar wind was provided through observations of comet tail deflections by L. Biermann in 1951. A cometary ion tail is oriented along the difference between the cometary and solar wind velocities, whereas the dust tail is in the antisunward direction; the ion tail directions demonstrated the existence of an outflow of ionized ...

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
