so the analysis of the coma by image processing and contrast boosting seems to show that there is stratification of the dust or gas sublimation ?
would this conform to the hypothesis that some thrusters are embedded in the object and they fire synchronously with the rotation period of the object to impart a trajectory change ?
the problem is that we have no "vanilla" object b to compare with, that has the same charateristics but no putative "thrusters". we'll see once there are more datapoints and doppler analysis to get a proper velocity vector. if that diverges from the orbital fitting, until then...
let's see in two weeks time.
