The processes that drive blue Haedus are not yet fully documented, but its brightness
seems to shift over a 24-day period. This hypothetical illustration shows the volatile star
casting off a 'shell' of plasma; one among many possible causes for its apparent variability.
A variable blue star in the constellation of Auriga, the Charioteer. This star is also known as Hoedus II, but its only connection
with Hoedus I (also called Saclateni) is that they appear to lie close together in the sky - in fact, they are
about 500 light years apart and are quite unrelated.
