In a new study published in Nature Astronomy, scientists have uncovered evidence that could help us better understand the evolution of oxygen in the universe. The researchers found that a merger between a white dwarf star and a low-mass companion star could be responsible for the oxygen found in some white dwarfs. This merger would effectively create a new star composed of neon and oxygen, which would make it a very different type of star than what we typically observe. This discovery could help scientists better understand how oxygen is created and distributed throughout the universe.
