Transition density ﹩\rho _{c}﹩ at which uniform matter becomes unstable to density oscillations as a function of the neutron skin in ²⁰⁸Pb. The solid curve is for the Z271 parameter set with ﹩\Lambda _{v}\neq 0﹩ while the dashed curve uses Z271 with ﹩\Lambda _{s}\neq 0﹩. The dotted curve is for the S271 set and the dot‐dashed curve for NL3, both of these with ﹩\Lambda _{v}\neq 0﹩.
