I know, this isn't the right place… but are we really going to blithely assume that because the radii distribution of objects in the ~0.3 - 70 Mjup interval is close to constant, there is no physical distinction between giant planets and brown dwarfs?
The notion is bizarre to me… that's a span in densities of over 2 orders. Can even a layman not hypothesise that this may cause structural differences? Does that not count for anything? Is there nothing that can be taken from the Herculean efforts it took to properly understand the relationship between stellar structure and the H-R diagram?
Regardless. I'm quite a fan of studies of brown dwarf companions, and that plus seeing the continuing use of ELODIE data after almost a decade since its decommissioning was pleasant to see.
It's rather remarkable that the orbital fit for HD 18757 is so well-constrained, considering how little of the orbit is covered. I suppose that's a testament to good periastron coverage.
