Scientists observing the red giant star R Doradus have found that starlight isn’t strong enough to drive its stellar winds, overturning a long-standing theory. The dust grains around the star are simply too small to be pushed outward by light alone. This raises new questions about how giant stars spread life-essential elements through space. Researchers now suspect dramatic stellar motions or pulsations may play a key role instead.
