We investigate new solutions for magnetized neutron stars with a barotropic core in magnetohydrodynamic (MHD) equilibrium and magneto-elastic crust, which was neglected by previous studies concerning MHD equilibrium. The Lorentz force of the star is purely irrotational structures magnetic fields are constrained. By contrast, solenoidal component exists elastic crust less restricted. find that m...

Results are presented in the theory of the elastic rod model for DNA, among which are criteria enabling one to determine whether a calculated equilibrium configuration of a DNA segment is stable in the sense that it gives a local minimum to the sum of the segment's elastic energy and the potential of forces acting on it. The derived stability criteria are applicable to plasmids and to linear se...
