A Woolf-Rayet star surrounded by gas that has been blown from its surface. The main difference between these stars and their less massive counterparts is that they steadily lose large amounts of mass throughout their short lives.
All stars lose material from their surfaces in a steady wind.
Our Sun loses on average two million metric tons of material every second. At this rate it would take 2000 times the present age of the universe to lose all its mass, so it is clear the solar wind will have no significant effect on the Sun's evolution. The solar wind blows past the Earth in puffs and clouds and some of it is drawn towards the Earth's magnetic poles causing displays of the aurora . The more massive the star, the greater the mass it loses in its stellar wind. Stars more than 50 times the mass of the Sun may lose over half their mass.
