Abstract
The deformation of nuclei in the neutrons star crust can be modelled by the system of two charged fluids separated by the phase boundary with non-zero surface tension. The stability of highly elongated structures, called pasta phases, is discussed here. In this work the cylindrical and spherical portion of charged fluids are considered. Their behavior depends on whether they are in vacuum or in charged surroundings what is modelled by Wigner-Seitz cell. The electric Bond number appears to be crucial parameter in the analysis. Variety of different unstable modes in vacuum case is strongly reduced in the case of W-S cell. It comes from the virial theorem, which bounds the value of the Bond number and reduces the role played by electric forces. Although the analysis is motivated by the nuclear pasta phases it can be applied to any system of two charged fluids.
