No skyrmion hair for stationary spherically symmetric reflecting stars

open access: yesPhysics Letters B, 2019
We investigate the existence of the skyrmion field in the background of an asymptotically flat stationary reflecting star. For this purpose, we consider the Einstein-Skyrme system for which there is a skyrmion hair in the black hole case.
