A rigorous theoretical investigation is made of arbitrary amplitude heavy nucleus-acoustic (NA) solitary waves (SWs) in a fully ionized multinucleus plasma system (consisting of thermally degenerate electron species (DES) and nondegenerate warm light as well as heavy nucleus species). The pseudo-potential approach, which is valid for the arbitrary amplitude SWs, is employed. The subsonic and supersonic NA SWs (which are found to be compressive) along with their basic features are identified. The basic properties of these subsonic and supersonic NA SWs are found to be significantly modified by the effects of non and ultrarelativistically DES, dynamics of heavy nucleus species, number densities as well as adiabatic temperatures of light and heavy nucleus species, etc. It is shown that the presence of heavy nucleus species with nondegenerate (isothermal) electron species supports the existence of subsonic NA SWs, and that the effects of electron degeneracies and light and heavy nucleus temperatures reduce the possibility for the formation of these subsonic NA SWs. The amplitude of the supersonic NA SWs in the situation of nonrelativistically DES is much smaller than that of ultrarelativistically DES but is much larger than that of isothermal electron species. The rise of adiabatic temperature of light or heavy nucleus species causes to decrease (increase) the amplitude (width) of the subsonic and supersonic NA SWs. On the other hand, the increase in the number density of light or heavy nucleus species causes to increase (decrease) the amplitude (width) of the subsonic and supersonic NA SWs. The results of this investigation are found to be applicable in the laboratory, space, and astrophysical plasma systems.
