Answer to Question 1

The surface of the star maintains a fairly constant temperature but the size continues to shrink significantly. Since the luminosity depends on the square of the radius, as the radius decreases by a factor of 100, the luminosity drops by a factor of 10,000. The slight increase in surface temperature changes the luminosity only a little.

Answer to Question 2

Protons and electrons are the main constituents of the solar wind.
