Scientific paper

We present new precise photoelectric observations of the Pre-Main-Sequence delta Scuti star, V351 Ori. These new data show that V351 Ori pulsates in a mixture of several radial modes (at least four). The comparison between observations and detailed pulsational models, allows us to provide independent constraints on the mass and luminosity of the star. The predicted distance is 210 pc, indicating that V351 Ori is much closer than the Orion star forming region. With an inferred mass of ~ 1.8 M_sun and an uncertain evolutionary stage, V351 Ori represents an excellent candidate for future asteroseismological studies that will assess whether it is a young PMS star ( ~ 6 Myr) or an evolved object ( ~ 1 Gyr) leaving the main-sequence.
