Astronomers figured out it is a binary object that is bright in x-rays and radio emissions. ... It appeared to be very close to a star called HDE 226868. However, that wasn't the source of the x-ray and radio emissions. It wasn't hot enough to generate such strong radiation.

WebX-ray star Cygnus X-1 and a radio star2 •3 , were those of a normal BOib supergiant. We made measurements of the radial velocity of the star from August 1971 to October 1971 … WebThe plot was generated using data from the optical spectrum of the star. The radial velocity we observe changes over time as the star orbits around Cygnus X-1. When the star is moving away from us, the velocity is positive. When the star is moving toward us, the velocity is negative. From this plot it is possible to determine the tangential ...
