This discovery reveals previously unnoticed dead stars in our immediate cosmic neighborhood. ## A significant distance record One of the discovered white dwarfs is now recorded as the ninth closest white dwarf to the Sun. Studying such nearby systems helps us understand stellar evolution processes. ## Binary star systems All detected white dwarfs are part of binary star systems. These systems are rare and interesting structures where a white dwarf orbits another star. ## Warwick and Colorado collaboration The discovery resulted from a joint effort by researchers at the University of Warwick in the UK and the University of Colorado Boulder in the US. The team used advanced observation techniques to achieve these significant findings. ## Importance of white dwarfs White dwarfs represent the final stages of stellar life cycles. Observations like these are crucial for understanding the ultimate fate of Sun-like stars. ## A significant step for astronomy This discovery will contribute to better mapping of star systems in our immediate cosmic environment. Astronomers continue their work to discover similar systems. ## Sources covering this story - https://phys.org/news/2026-07-dead-stars-cosmic-backyard-astronomers.html — --- _Summary written by Brifing from the original reporting.
