  text: The recent detection of solar equatorial Rossby waves has renewed interest
    in the study of gravito-inertial waves propagating in the convective envelope
    of solar-type stars. In particular, the ability of these envelope gravito-inertial
    modes to couple with those trapped in the radiative interior could open up new
    opportunities for probing the deep-layer dynamics of solar-type stars. The possibility
    for such a coupling to occur is particularly favoured among pre-main-sequence
    (PMS) solar-type stars. Indeed, due to the contraction of the protostellar object,
    they are able to reach high rotation frequencies before nuclear reactions are
    ignited and magnetic braking becomes the driving mechanism for their rotational
    evolution. In this work, we studied the coupling between the envelope inertial
    waves and the radiative interior g modes in PMS stars, focussing on the case of
    prograde dipolar modes. We considered the cases of 0.5 M⊙ and 1 M⊙ PMS models,
    each with three different scenarios of rotational evolution. We show that for
    stars that have formed with a sufficient amount of angular momentum, this coupling
    can occur in frequency ranges that are accessible to space-borne photometry, creating
    inertial dips in the period spacing pattern. Using an asymptotic analysis, we
    characterised the shape of these inertial dips to show that they depend on rotation
    and on the stiffness of the convective-radiative interface.
