| Abstract: | Recently, Li and Liu have studied global monopole of tachyon in a four dimensional static space–time. We analyze the motion of massless and massive particles around tachyon monopole. Interestingly, for the bending of light rays due to tachyon monopole instead of getting angle of deficit we find angle of surplus. Also we find that the tachyon monopole exerts an attractive gravitational force towards matter. |
