Odd-parity gravitational perturbations of a spherically symmetric background are studied in the linearized Einstein theory. A variety of collapse models, based on a May-White hydrodynamic code, are investigated, simulating dust collapse and stellar core collapse typical of type-II supernova models. Numerical results are presented, showing that in this linearized problem a typical core collapse may radiate up to ${10}^{\mathrm{-}7}$ ${\mathrm{Mc}}^2$ in gravitational-wave energy.
