proposal
The overall objective of this proposed effort is the development
of a semi-empirical, time independent MHD model of the steady
state and azimuthally symmetric corona
and solar wind during the quiescent phase of the solar cycle.
Close to the Sun,
the model will use as inputs 1) an emperically derived azimuthally
symmetric electron density distribution, and 2) an empirically
derived model of the magnetic field topology obtained from the
observed streamer/coronal hole boundaries and polar rays/plumes
from LASCO/EIT observations.

At 1 AU, the model requires an estimate of the solar wind mass
flux and radial component of the magnetic field as a function of
latitude which can be obtained from the in situ observations
by the Ulysses spacecraft. The model makes estimates as a
function of radial
distance and latitude of various fluid parameters of the
plasma such as flow velocity v, temperature
Teff, and heat flux qeff which are derived from the equations of
conservation of mass, momentum and energy, respectively.


This proposal has been funded by the SOHI GI Program.
