<p>I am studying some binary stars and brown dwarfs. Some orbits are known and easy to find, like Alpha Centauri. However, when I look for the orbital characteristics of Luhman 16 (AB), I only get the right ascension and declination of the entire system. I can convert that to <span class="math-container">$(x,y,z)$</span> coordinates, but is there any defined orbit for Luhman 16 AB?</p>
<p>I've tried looking it up on Arxiv, but the results do not give any information regarding their orbit. Is there any resource that provides information about this subject?</p>

Have you seen the [Wikipedia page on the system](https://en.wikipedia.org/wiki/Luhman_16#Orbit_and_masses).  There are links to papers there.  Not really sure what you mean by "rectangular coordinates".

The orbital parameters are given in Lazorenko & Sahlmann 2018, [Updated astrometry and masses of the LUH 16 brown dwarf binary](https://www.aanda.org/articles/aa/full_html/2018/10/aa33626-18/aa33626-18.html), Table 5.
