UVCS Scientific Purpose
The purpose of the UVCS is to provide a detailed description of the extended
solar corona that can be used to address a broad range of scientific questions
regarding the nature of the solar corona and the generation of the solar
wind.
UVCS makes measurements of the solar corona between 2 and 10 solar radii
from sun center with high spectral and spatial resolution. From the spectroscopic
measurements at ultraviolet wavelengths, the
-
proton velocity
distribution,
-
proton outflow
velocity,
-
electron temperature,
and
-
O VI, Si XII,
and Mg X outflow velocities and densities
can be determined. Information about the
-
O VI, Si XII,
and Mg X velocity distributions,
-
electron density,
and
-
minor ions
densities
can also be learned.
