Can 'failed stars' have planets? James Webb Space Telescopes offers clues

[Admin]

The James Webb Space Telescope has discovered brown dwarfs at the heart of planet-forming disks in the Orion nebula. The discovery could help reveal if these "failed stars" can have planets.

The interesting thing about protoplanetary disks around brown dwarfs is that they could allow us to see how a star's ignition of fusion changes the nature of the disks and what types of planets form around them. With no stellar "wind" to cause gases and dust to blow away from the non-star, I would expect any planets that form to have gases and ices similar to the outer planets and Kuiper Belt objects in our solar system, but much closer to the non-stars.

I also have to wonder if brown dwarfs continue to accumulate mass such that some eventually become red dwarfs. Is mass from their disks still falling into them? Does other mass from their large star-forming nebula continue to be attracted into the disks and maybe directly into the brown dwarfs?
