Contribution
It provides new insights into cylindrical geometries, particle motion, and matching conditions in Brans-Dicke theory, connecting them to the GR limit.
Findings
Particle trajectories in vacuum cylindrical solutions are characterized.
The nature of global string metrics in Brans-Dicke gravity is analyzed.
Junction conditions for cylindrical solutions are derived and compared to GR.
Abstract
Several points regarding cylindrical Brans-Dicke geometries are studied. The issue of particle trajectories for the vacuum cylindrical solution is revisited. The possible particular nature of a global string metric is analysed. The general form of the junction conditions for matching cylindrical solutions within this theory is written down, and the relation with the general relativity limit is discussed.
