Orbit of AB Doradus C
July 16, 2007
The orbit of AB Doradus C around its more massive companion, AB Doradus A, is shown as a green ellipse. AB Doradus takes 11.75 years to make a full orbit, the separation on the sky being only ~0.2 second of arc. This orbital solution (which implies a mass of 0.09 solar mass for AB Doradus C) was obtained from Hipparcos/VLBI astrometry, and is confirmed by the last 5 AO images obtained by the present team.
