Iota Arae, Latinized from ι Arae, is the Bayer designation for a star in the southern constellation of Ara. It is 920 light-years (281 parsecs) from Earth, give or take a 20 light-year margin of error, and has an apparent visual magnitude of 5.2. Based upon the Bortle Dark-Sky Scale, this means the star is visible to the naked eye from suburban skies.

This is an evolved subgiant star with a stellar classification of B2 IVe.[3] The 'e' notation indicates the spectrum displays emission lines, which means this is a Be star that is surrounded by hot, circumstellar gas. It is spinning rapidly with a projected rotational velocity of 340 km/s. The Doppler effect from this rotation is causing the absorption lines to widen and become nebulous, as indicated by the 'n' notation in the stellar class. It is a spectroscopic binary, and is in an orbit with a second, smaller component, a subdwarf O star.[3]

A light curve for Iota Arae, plotted from TESS data[11]

Iota Arae has around 8.3 times the mass of the Sun and is shining brightly with 10,864 times the Sun's luminosity. This energy is being radiated into space from the outer atmosphere at an effective temperature of 20,172 K, giving it the characteristic blue-white hue of a B-type star.[12] The General Catalog of Variable Stars classifies it as a BE variable star, ranging from visual magnitude 5.18 to 5.26 with a period of 13.36 hours.[2] In a study of the Hipparcos data, it was found to vary in brightness by 0.054 in magnitude with no clear period.[13]
