- Abstract
- We consider a global monopole spacetime with Newman-Unti-Tamburino (NUT) charge ill the Brans-Dicke theory and determine, within the weak gravity approximation, the asymptotic structure of the spacetime whose origin coincides with a galactic center. We discuss its implications for stellar rotation curves of the galaxy with a softened isothermal dark halo.
