R Sculptoris is an asymptotic giant branch semi-regular variable red giant star located 1,500 light-years (460 parsecs) away in the constellation of Sculptor.[3][2][4] Observations have revealed a spiral structure in the material around it.[5] The spiral is suspected to be caused by an unseen companion star.[3]
