Epsilon Apus
Variable starWhat is Epsilon Apus
Epsilon Apodis is a hot blue type B star burning some 645 light-years away, in the Bird of Paradise, a southern constellation drawn in the sixteenth century by Pacific explorers. It is a Be-type variable: every so often it sheds gas from its atmosphere and wraps itself in a short-lived disc that subtly alters its brightness. A restless star in one of the most remote corners of the southern sky.
