Evidence for a very young age of F stars with extrasolar planets.
SUCHKOV A.A. and SCHULTZ A.B.
Abstract (from CDS):
We assess the age of nine planet-bearing (PB) F stars by comparing their metallicity, Hp variability, brightness anomaly, and location in the color-magnitude diagram with the same parameters for the Hyades and field F stars. Combined evidence from these parameters suggests that the age of our PB F stars is not very much different from the age of the Hyades, ∼700 Myr, and is much younger than the ages of cooler, solar-type PB stars found in a number of recent studies.
