Science with SOHO.
Abstract
The scientific goals of the Solar and Heliospheric Observatory (SOHO) comprise the basic and interconnected questions regarding the interior structure of the Sun, the heating of the corona and its expansion as solar wind. The observations needed to pursue these questions will be taken from a halo orbit around Lagrange point L1 on the Earth-Sun line, which offers uninterrupted observations of the Sun and - lying outside the magnetosphere - of its solar-wind streams. In this paper the authors outline some patent solar and heliospheric problems, define the resulting observing needs and present the SOHO model payload (helioseismology, optical plasma diagnostics of the corona at extreme ultraviolet (XUV) and visible wavelengths, in-situ particle and field measurements) in the light of these requirements.
