FfFfFfFF 58,083 Posted September 15, 2021 Share Posted September 15, 2021 An international team of astronomers has detected a new peculiar binary as part of the Sloan Digital Sky Survey (SDSS). The newly found object, designated SDSS J133725.26+395237.7, is a nearby double-lined system consisting of two white dwarfs. Astronomers are interested in finding and studying double white dwarfs (DWDs), as their mergers are believed to produce new white dwarfs with higher masses. It is assumed that some high-mass white dwarfs in the solar neighborhood could be DWD merger products. The number of known SB2 white dwarf systems with well-measured mass and orbital parameters is still relatively small. Finding new objects of this type could be crucial in order to advance our knowledge about double white dwarfs in general. The researchers emphasized that due to its proximity to Earth and short period, SDSS J1337+3952 is among the strongest known sources of gravitational waves in the millihertz frequency regime.
