Using a novel eigenfunction matching procedure in numerical simulations, we show that oscillation modes of a newly born neutron star can imprint on both gravitational waves and neutrinos. The mechanism of imprint on neutrinos is via direct hydrodynamic modulation of the neutrinospheres. This implies that neutrinos carry information on the coherence and amplitude of oscillation modes at specific radii within the neutron star, potentially providing detailed asteroseismological information. However, the prospects for detection with current technology are low.
