In this talk\, I will present two separate projects related to the imprints of stellar oscillations on the gravitational wave (GW) sig nals. In the first project\, we consider the signals from binary hybrid st ar (HS) coalescence events. The HS is a special type of neutron star which  \;core is made of deconfined quark matter. We show that the HSs have a special oscillation mode associated with the nuclear matter-quark matter phase transition that can potentially resonate during the inspiral stage\ , producing effects in the GW signal measurable by the ground-based detect ors. In the second project\, we study the effect of dynamical tide on ecce ntric binary white dwarf systems. We show that the non-resonant buildup of the oscillation modes can produce an orbit precession resolvable by the u pcoming space-based GW detector. For orbits with high eccentricities and s mall pericenter separations\, it can even cause the waveform to become cha otic.
