Object: Orbital physics detects star NOT dwarf
Hubble could not see it, but the 8.2 meter in Chile using adaptive
optics got the image and the orbit of AB Doradus C -- finding important
because at 93 Jupiter masses it makes the "star" cut and retools the
mass luminosity curve for this class of objects:

Cute!
One little question, though.
How do you find the orbit, and what are the parameters?
Y'know, trivial stuff, like eccentricity, major axis, inclination, *****
like that?

You should know - you invented the technique: they run your
stupid program and fiddle with the parameters until they can
reproduce something that resembles the luminosity curve.
