The fundamental parameters of the roAp star gamma Equulei

Thanks to the unique capabilities of the spectro-interferometer VEGA, the authors were able to derive a value of 0.564 mas for the angular diameter of the rapidly oscillating Ap star gamma Equ with an accuracy of about 3%, and derive its fundamental parameters, thus bringing further constraints on the asteroseismic modeling of this star.
