Description: The second important journal article on the first scientific evidence of a black hole at Cygnus X-1. The abstract to the . article states, "Recent observations of the binary star HDE 226868, which is believed to be associated with Cygnus X-1, are here combined with data already published to obtain improved orbital elements for the binary system. The data imply that the secondary is a black hole."; Bolton, C.T. (1972). Dimensions of the Binary System HDE 226868 = Cygnus X-1. Nature Physical Science, 240 (102): 124-127.
