Characterizing which graphs are determined by their spectra is a very interesting problem. Recently, many researchers have paid attention to this problem, and many graphs have been proven to be determined by their spectra. In this paper, the authors proved that the so-called wind-wheel graphs are determined by their Laplacian spectra as well as by signless Laplacian spectra. The results are interesting and enlarge the family of graphs determined by their spectra.
