Hot blue starIts story
Theta Lupi is a blue main-sequence star spinning at a dizzying 331 km/s at its equator. That rotation deforms it: its equatorial diameter is roughly 15% larger than its polar one, a sphere flattened by its own momentum. At 415 light-years inside the Wolf, it is one of those hot, young beacons still in the bloom of its evolution.
