Gam

Its story

Gamma Trianguli marks one corner of the tiny Triangulum, the austere figure traced by three white stars north of Aries. It is an A-type star 112 light-years away, young and hot, spinning so fast that it flattens slightly at the poles. Around it, infrared observations have revealed a dusty disc: the cold remains of a forming system, distant cousins of the rings seen around the youngest stars in the solar neighbourhood.
