Variable starIts story
σ Puppis is an orange giant that pulses slowly, varying its brightness in long cycles like a stellar breath. It belongs to the ancient stern of the ship Argo, divided in the 18th century into three constellations: Carina, Vela and Puppis. Its warm K-type light suggests a star well into its later life, swollen and golden in the southern latitudes of the sky.
