Sur Wikipedia ils ont une description de ce microquasar que je n'arrive as trop à décrypter, ils parlent de relativité générale, qu'en est il vraiment ?
"The spectrum of SS 433 is affected not just by Doppler shifts but also by relativity: when the effects of the Doppler shift are subtracted, there is a residual redshift which corresponds to a velocity of about 12,000 kilometers per second. This does not represent an actual velocity of the system away from the Earth; rather, it is due to time dilation, which makes moving clocks appear to stationary observers to be ticking more slowly. In this case, the relativistically moving excited atoms in the jets appear to vibrate more slowly and their radiation thus appears red-shifted".
