This is a Demonstration of the Parker model (Parker 1958) for the solar wind. The plot shows the solar wind flux velocity as a function of the distance from the Sun. The temperature
T
is assumed to be constant. You can change its value to see how it influences the resulting velocity. Distance is expressed in astronomical units (1 AU = 149 598 000 km). The blue dashed line indicates where the velocity equals the sound speed. The black dashed line shows the location of the Earth.
