Brown dwarfs blur the lines between stars and planets. Brown dwarfs are curious celestial bodies that appear to straddle the mass divide between stars and planets. Often referred to as "failed ...

Due to their close proximity, the white dwarf strips mass from its low-mass companion. This process has removed about 90 per cent of the mass of the companion, turning it from a star into a brown ...

Brown dwarfs are lighter than stars, and heavier than gas giants like Jupiter. And while astronomers had measured the mass of Gliese 229B to be about 70 times that of Jupiter, an object of that ...

"Brown dwarfs, planets or stars" JuMBOs play charades with astronomers As explained above, the big mystery about JuMBOs is they seem to defy the formation avenues that lead to both stars and planets .

These cool, dim stars are known as brown dwarfs or 'failed stars.' But even the mass of a brown dwarf isn't enough to overcome the Coulomb barrier and start up stellar fusion. Fusion takes so much ...

This volume provides a state-of-the-art review of our current knowledge of brown dwarfs and very low-mass stars. The hunt for and study of these elusive objects is currently one of the most dynamic ...

I say planet-like because brown dwarfs are not actually considered stars or planets. In fact, they straddle the line that divides planets and stars. They form similarly to other stars. However ...

Using the James Webb Space Telescope, astronomers have discovered that planet-forming disks in the Orion nebula actually ...

Meet the brown dwarf: bigger than a planet, and smaller than a star. A category of its own, it’s one of the strangest objects in the universe. Brown dwarfs typically are defined to have masses ...
