It is well known that distribution of density of hadron matter in neutron star interior is stratified. In proposal model, the structure of neutron star is treat like the stiff core surrounded by dynamical layer. The underlying physical assumption is that stellar matter of outer layers has elastic properties and its dynamical behavior is described by nuclear elastodynamics equations. It was shown that vibration dynamics of neutron star is characterized by two branches of nonradial spheroidal (s-mode) and torsional (t-mode) gravitational-elastic eigenvibrations. From numerical value of periods of nonradial vibrations it follow that observable variations in the intensity of micropulses detected from C-pulsars can be assigned to their nonradial gravitational-elastic eigenvibrations. The proposal bicomponent model of neutron star allows to say that confusion in radio pulses of pulsar is the starquake called by companion of binary star system.
