Jupiter-sized objects in Orion Nebula baffle scientists. The new entities, nicknamed ‘JuMBOs’, are neither stars nor planets. And they shouldn’t exist, researchers say. (www.aljazeera.com)

The article says that they're binaries, and that the prevailing scientific opinion says they were ejected from young star systems as they form.

I'd like to see the gravitational context in which 2 Jupiter sized masses are flung out of a system together.

Maybe it's rare and we're seeing those few times it happened?

(No I'm not saying it's aliens. Just that I want to understand how a binary leaves a star system. Wouldn't the ejection gravity "assist" also fuck up the binary attraction?)

Just consider the binary as a single object, and it's easy enough to imagine it getting flung out.
