AB Dor C
Orbit of AB Dor C


An enhanced false color infrared image of AB Dor A and C. The faint companion AB Dor C – seen as the pink dot at 8 O'clock – is 120 times fainter. The tiny 0.156 arcsec separation between A and C is smaller than a dime seen from 8 miles away. Nevertheless, the new NACO SDI camera was able to distinguish it as a "redder" dot surrounded by the "bluer" light from AB Dor A. The computed orbit of the companion around the primary is shown.
