I have a common envelope simulation where two stars orbit each other. The cores of the stars are approximated by point-masses.

I would like to move my coordinate system on the core of one of them with the x axis aligned with the semi-major axis of the orbit, so as to be able to analyse the data in a co-rotating coordinate system.

Is there any pre-built function in yt that allows moving the coordinates system to a specific point of the box and rotate them? Or I have to do it manually?

Thanks,

Roberto
