description Tiaki Overview
Tiaki, formally designated Beta Gruis, is the second-brightest star in the southern constellation Grus. It is an evolved red giant on the asymptotic giant branch, with a cool surface and an M-type spectral classification. Beta Gruis is also a semiregular variable star, meaning that its apparent brightness changes over time without the strictly repeating cycle of a classical periodic variable. At roughly second magnitude, it is visible to the unaided eye and serves as a useful reference star for observers of Grus.
