TESS discovers a rare brown dwarf orbiting a massive, aging star
For decades, astronomers lumped brown dwarfs into a single category defined by mass alone—too big to be classified as planets but too small to become stars. However, this definition ignores the two very different mechanisms that can form them: the direct collapse of gas clouds and formation within the accretion disks of massive stars.
We haven't written up this one. Phys.org has the full story — the link below goes straight to it.
