摘　　要：By considering an asymmetric thin-shell wormhole(ATSW)surrounded by an optically and geometrically thin disk,we investigate the luminosity distribution of this ATSW with the spacetime on two sides encoded with the renormalization group improved(RGI)parameters(Ω,γ).Although some light rays are absorbed into the throat in the vicinity of the wormhole,they return through the throat with certain conditions,unlike in the case of black holes.The spacetime on one side of the wormhole can capture the additional photons emitted from the thin disk,resulting in several interesting observable features of the wormhole.The results in this paper show that there are two additional orbit numbers n in the ATSW and six transfer functions,rather than three as in the black hole case.In this case,the ATSW indeed has a more complex observable structure,where some additional light rings arise naturally.For instance,there are two additional photon rings for the emitted Model 1.Moreover,we also find a new wide hump between the first and second additional photon rings in Model 2.The effects of Ω and γ on the observed images are clearly addressed throughout this study,and the influence of Ω is found to be larger.Finally,we conclude that the observations of the RGI-ATSW can help further distinguish it from other ATSWs and black holes when a thin accretion disk exists around it.
