Abstract
New photometric observations of seven intermediate mass pre-main
sequence ![[FORMULA]](img1.gif)
Scuti candidates are
presented. The periods and pulsation modes are derived for two of
these stars, namely HD 35929 and V351 Ori. The comparison
between observations and nonlinear pulsational models allows us to
provide some initial constraints on their mass and evolutionary state.
As an illustration we discuss the use of periods to identify the mode
of pulsation in these two stars and to have an independent estimate of
their distances.
