Jupiter-mass object in CD-35 2722

That is a great point... if we can actually tell them apart, it means we could find rogue planets that got captured by brown dwarfs... imagine the diversity of atmospheres we could find in those weird pockets of space!
Why are we calling this a satellite? If the mass ratio is too close, this is just a binary brown dwarf system. Where is the evidence for a primary-secondary relationship?
If the mass ratio does lean toward a binary system, would that change how we view the formation of the CD-35 2722 system as a whole?
The use of the VLT's high-contrast imaging is critical here, as the luminosity ratio between a brown dwarf and a Jupiter-mass object is incredibly tight. This finding should be read alongside recent shifts in how we model sub-stellar mass thresholds; it challenges the traditional boundary between planetary formation and gravitational cloud collapse.
This reminds me of the early Planet Nine predictions. We see a signal that fits the model, but the data often smooths out once the sample size increases.
It is like trying to classify a duplex versus a semi-detached home in city zoning. The labels matter for the paperwork, but the building functions the same regardless of what the code calls it.
the labels matter less than the orbital stability of a world with no central sun.
If we assume labels are irrelevant, we might overlook the distinct chemical signatures that differentiate a captured planet from a co-formed binary. Wouldn't the nomenclature actually guide the search for those specific markers?
