India, Jan. 6 -- The Government of India has issued a release:
A study of a type of stellar twin called W Ursae Majoris-type contact binaries that orbit each other closely gives new insights into how binary stars evolve and their eventual fate.
W Ursae Majoris (W UMa) stars are short-period, dumbbell-shaped binaries in which the two stars are in contact. They are so close, in fact, that they share a single outer atmosphere and they orbit around each other. These stars act as "natural laboratories" as they assist in precise determinations of fundamental stellar parameters such as masses, radii, and temperatures, crucial for testing theories about how stars evolve over time.
