Eggen lists it as a member of the old disk population.
This is an evolved red giant star with a stellar classification of K3 III. It is currently on the red giant branch, generating energy by fusing hydrogen in a shell around its core. It has 4.8 times the mass of the Sun and an enlarged radius of due to its evolved state. It radiates 915 times the luminosity of the Sun from its photosphere at an effective temperature of. HD 31529 is slightly metal deficient and spins modestly with a projected rotational velocity of.
