Janus: The Enigmatic Two-Faced Star

Scientists have discovered a unique white dwarf star, nicknamed Janus, which is composed of hydrogen on one side and helium on the other. Located in the Milky Way galaxy, Janus rotates every 15 minutes and is larger than our sun but with a diameter half that of Earth. This peculiar star may be in the midst of transitioning from a hydrogen atmosphere to a helium atmosphere. The researchers suspect that its magnetic field may be responsible for this asymmetry. Janus represents a rare glimpse into the transitional blending process of white dwarfs and highlights the diverse nature of stellar phenomenology.
