"Lonely Ageing Brown Dwarfs: Hubble's Surprising Discovery"

A recent survey using the Hubble Space Telescope has found that ageing brown dwarfs, which are larger than Jupiter but smaller than stars, are less likely to have companions as they get older. This suggests that binary pairs of brown dwarfs do not survive over time, likely due to the weak gravitational hold between them and the disruptive influence of passing stars. The survey provides evidence that most brown dwarfs remain single for the majority of their long existence, supporting the theory that they are born the same way as stars but do not have enough mass to sustain nuclear fusion.
