Thats why we should have an open mind as scientists...

stating you know everything is a blashemy to nature
I agree. I find many of the responses in this thread appalling with regard to what people say about scientists, who apparently don't know any real scientists, because as you correctly say, scientists don't think they know everything, and they wouldn't become scientists if they didn't think we had more to learn.

You will not find one scientist of any credibility that states they know everything.
If we knew everything we wouldn't NEED science.
I don't understand why some people don't understand that. I guess it is because basic science education is poor in many places.
I see you go on to present the more plausible failed binary star idea which is good. Yes it would be rare to capture an orphan planet and it doesn't take a lot of physics to understand why. First the distances between stars is so immense orphan plants can travel long distances without ever making close approaches to stars, but even in the rare event they do, far more likely than being captured is some kind of "slingshot" interaction away from the star in some other direction. NASA has used many of these slingshot interactions between their satellites and planets in our solar system to alter their course, change the velocity, etc.

It may be that they found an exceedingly rare object: A captured orphan.
As that article confirms it is an idea that shouldn't be ruled out but it also explains the clues we would look for to confirm it, such as whether the orbital plane is different from the orbital plane of other planets formed from the protoplanetary disk.
Astronomers haven't detected any clear-cut cases of captured planets yet.

Most of the stars in our galaxy are binaries
In this Letter I compare recent findings suggesting a low binary star fraction for late-type stars with knowledge concerning the forms of the stellar initial and present-day mass functions for masses down to the hydrogen-burning limit. This comparison indicates that most stellar systems formed in the Galaxy are likely single and not binary, as has been often asserted. Indeed, in the current epoch two-thirds of all main-sequence stellar systems in the Galactic disk are composed of single stars. Some implications of this realization for understanding the star and planet formation process are briefly mentioned.

Just goes to show that the current paradigm in astronomy really doesn't explain everything. I have always had an inkling of a thought that a large portion of the currently accepted theories about space and the universe should be held in that regard... theories. until we can traverse the cosmos (farther than earth orbit) we will never really know if these theories are right.
There are alot of people (that i know, and on ATS) who take the current theories as 100 percent proof. I guess when people with Ph'D's and the like say something their word is law.

Back to the OP topic, it seems more a case of binary star formation (failed) and we have lots of binary star systems so it shouldn't be surprising that some binaries don't have enough mass of the right type for fusion to occur.

The truth is we don't really know how rare it is because we really haven't found a good example of a captured planet yet:
