摘要：
We present new results of our kinematic study of the supernova remnant S8 in the galaxy IC 1613. Based on our observations at the 6-m Special Astrophysical Observatory telescope with the two-dimensional MPFS spectrograph and the SCORPIO focal reducer in the mode of a scanning Fabry-Perot interferometer, we have determined the expansion velocity of the bright optical nebula. Analysis of the 21-cm VLA radio observations for the galaxy confirms our previously suggested model for a supernova explosion in a cavity surrounded by a dense HI shell and a collision of S8 with the shell wall.
