Dead stars in our cosmic backyard: Astronomers spot four white dwarfs hiding under our noses

Astronomers from the University of Warwick and the University of Colorado Boulder have discovered four previously hidden white dwarfs in binary star systems within 65 light-years of Earth. Each system includes a red dwarf star, making the white dwarfs difficult to detect due to the brightness of their companions. Using ultraviolet data from the Hubble Space Telescope, researchers identified these white dwarfs by analyzing subtle wobbles in the red dwarfs' motion, which indicate the presence of a massive companion. One of the systems, G 203-47, is especially intriguing because its red dwarf rotates much slower than expected, suggesting unique evolutionary processes compared to other similar systems.
