So Chile has a distinct status, hence the margin...?
> The star is being orbited by a brown dwarf, an object too massive to be a planet but too small to be a star.
That being said it is still a nice finding, way more difficult to discover than "normal" exopanets.
Isn't the dividing line between the largest possible gas giants and the smallest brown dwarfs a bit fuzzy?
The exact model limit is unclear, but the physics modelling is relatively straightforward.
see the Classification header of the page
“A subsatellite, also known as a submoon, moonlet or informally a moonmoon, is a "moon of a moon" or a hypothetical natural satellite that orbits the moon of a planet”
Look at Barnard's Star[1], which is actually a fusing red dwarf star: it is not much bigger than Jupiter.
That does not appear to be the case if we mean mass, not diameter.
You could basically have a bath in a brown dwarf, sure you might not last long, but still...
