The primary component is an evolvingG-typesubgiant star with a stellar classification of G8 IV. It is about 1.6 times the mass of the Sun and has 4 times the Sun's radius. The star shines with 10 times the solar luminosity from its outer atmosphere at an effective temperature of 5,115 K. Unusually for a star of this class, it shows a photometricvariability of 0.04 in magnitude, which may be due to a previous mass transfer from the secondary companion, or else from an undiscovered third companion.
The companion is about 7 magnitudes fainter than the primary and may be the source of the X
-ray emission from this system. This emission has a luminosity of 504.4×10 erg s.
