Article has failed to mention the fact that Vega is a He core burner with 1/3 the metallicity of the sun and that it has already been through the H burning red giant stage.

The star is currently also a delta scuti variable with relatively small overlapping pulsations, as the evolutionary next step from the Ap type Alpha canum venaticorum variables that result from the helium flash of a relatively medium mass star (originally of type F on the main sequence.

Its true age will be a feature of Vega's mass which can only be really gained when the orbital period of a planet is found around it.

Being a giant and brightening slowly due to the more rapid progress of He core burning, the interior planetary system will be rather hot and should be visible via comet reactions if small and close enough.

Happy hunting.

Have a nice day; Ag
