At the pole, the temperature may be above 20, 000 K, while the equator is at or below 10, 000 K. The average temperature of the star is about 15, 000 K. The high polar temperatures are generating a fast polar wind that is ejecting matter from the star, creating a polar envelope of hot gas and plasma.
