Astronomers have confirmed four white dwarf stars previously hidden in binary systems within 65 light-years of Earth. One system, located just 25 light-years away, ranks as the ninth closest known white dwarf to the Sun.

Researchers have discovered that tidal forces in tightly orbiting binary white dwarfs generate significant internal heat, causing the stars to expand and reach unexpectedly high temperatures. This phenomenon challenges previous models and could explain the early onset of cosmic interactions like supernovae. The findings come from a study led by Kyoto University.
