Astronomers predict an unseen class of star-like our bodies known as “darkish dwarfs” close to our galaxy’s middle. A brand new research suggests these objects might shine because of annihilating darkish matter, not nuclear fusion. Darkish matter makes up a couple of quarter of the universe and interacts through gravity. If WIMP-like darkish matter particles acquire in a brown dwarf, they’d annihilate and warmth it, inflicting a faint glow. Darkish dwarfs can be too mild to fuse hydrogen, however would preserve lithium-7 of their atmospheres, providing a signature. This prediction comes from a JCAP research. The invention of 1 might reveal darkish matter’s nature.
