Lone spinning stars may be 'runaways': a supernova explosion flings them like a stone from a sling, giving them speeds of 24 km/s or more. This explains how up to 22% of enigmatic solitaries are born—a fresh take on an old puzzle.
🎯 The 'e' in Be stars stands for 'emission'—radiation. It occurs because rapid rotation tears gas from the star's equator, forming a bright disk.
