New Delhi: In a remarkable astronomical breakthrough, a team of scientists has made an intriguing discovery - a unique white dwarf star with an extraordinary dual nature. Dubbed "Janus," after the ancient Roman god with two faces, this celestial gem resides approximately 1,300 light-years away in the Ursa Major constellation.
What sets Janus apart is its captivating dichotomy. The star boasts two distinct hemispheres, each characterized by its own temperature and elemental composition. On one side, Janus burns fiercely at an astonishing temperature of 10,000 degrees Celsius, while on the other, it remains considerably cooler at around 3,000 degrees Celsius. This temperature asymmetry is accompanied by a fascinating difference in its chemical makeup, with the hot side being helium-enriched and the cool side dominated by hydrogen.
Astronomers believe that Janus's remarkable features are the aftermath of a spectacular cosmic event - the merger of two smaller white dwarf stars. The merger triggered rapid rotation, causing the star to flatten into its current two-faced configuration. Consequently, Janus's hot side perpetually faces the axis of rotation, while the cooler side points in the opposite direction.
The discovery of Janus holds profound implications as it offers unprecedented insights into the intricate evolution of white dwarf stars. These celestial objects represent the final phase in the life cycle of most stars and play a crucial role in our comprehension of the universe's workings.
