In this article there is a lot explained about planets orbiting a binary star. It is said that a planet orbits the binary star around the CM of both stars. I couldn't find anything about planetary orbits (neither in other articles) of planets tracing out an $\infty$-form around the two stars. This picture in this article is showing the path I mean (the red line):

enter image description here

In the article, though, the red line isn't representing the trajectory I mean (I used it only to clarify what I mean), but it represents the (as is shown) the Roche lobes, which are explained in the article.

I think my question is clear by now: do there exist orbits of planets in a binary star system which make the trajectory I described?
