 It is a marginal barium star, showing an enhanced abundance of s-process elements in its outer atmosphere.This material may have been acquired during a previous mass transfer from a now white dwarf companion, or self-enriched by a dredge-up during the AGB process.The measured angular diameter after correctly for limb darkening is , which, at the estimated distance of this system yields a physical size of about 74.5 times the radius of the Sun.
