Abstract: In addition to the boosted static solution there are two other classes ofstationary string-like solutions of the vacuum Einstein equation in4+1-dimensions. Each class is characterized by three parameters of mass,tension, and momentum flow along the fifth coordinate. We analyze the metricproperties of one of the two classes, which was previously assumed to be nakedsingular, and show that the solution spectrum contains black string andwormhole in addition to the known naked singularity as the momentum flow tomass ratio increases. Interestingly, there does not exist new zero momentumsolution in these cases.
