HD 97413 is a binary star located in the southern constellation Centaurus. The system has a combined magnitude of 6.27,[3] placing it near the limit for naked eye visibility. Based on parallax measurements from the Gaia spacecraft, the system is located 320 light years away from the Solar System.[2]
The objects binarity was detected in a Hipparcos survey. The two components can't be distinguished because both stars have an angular separation of 0.01″.[11] Nevertheless, speckle interferometry revealed the components to have a 2.6 magnitude difference.[12] They are located along a position angle of 250°.[11]
The visible component – HD 97413 A – has a stellar classification of A1 V, indicating that it is an ordinary A-type main-sequence star. It has 1.94 times the mass of the Sun[6] and a radius of 2.18 R☉.[7] It radiates 19.6 times the luminosity of the Sun[8] from its photosphere at an effective temperature of 7,800 K,[8] giving it a white hue. However, this is not typical for an A1 star. Parameters determined by Gaia's extinction reveal HD 97413 A to have an iron abundance half of the Sun's,[9] making it metal deficient.
