a subsequent work derived an older age of million years based on the star's position on the Hertzsprung-Russell diagram position assuming that the star is not a fast rotator viewed pole-on. Direct measurements of the star later showed that Kappa Andromedae A is in fact a rapid rotator viewed nearly pole-on and yield a best-estimated age of 47 million years. Modelling of the companion Kappa Andromedae b further constrains the age to million years.
