Twin-sun worlds: 27 circumbinary planet candidates spotted in latest survey

A new survey using data from NASA’s TESS telescope identified 27 strong circumbinary planet candidates orbiting binary star systems (out of 1,590 binaries), suggesting there could be thousands of such planets hiding in the galaxy. Planets are inferred from variations in the stars’ eclipse timings, and while the candidates range from Neptune-sized to up to Jupiter-sized, they require future observations to confirm their status.

Two-Sun Worlds: 27 Candidate Circumbinary Planets Uncovered

Astronomers using apsidal precession timing of eclipsing binary stars and NASA’s TESS data identified 27 new candidate planets that would orbit two stars. Distances range from 650 to 18,000 light-years, adding to about 18 previously known circumbinary planets. Follow-up spectral analysis is needed to confirm whether these bodies are planets (likely Neptune-sized to ~10 Jupiter masses) or brown dwarfs/stars. The study was published in Monthly Notices of the Royal Astronomical Society.

Einsteinian Gravity Explains Why Circumbinary Planets Are So Rare

A new study shows general relativity alters the three-body dynamics around tight binary stars, progressively destabilizing circumbinary planets and helping explain their scarcity and the difficulty of detecting them.

Astronomers discover Tatooine-like exoplanet orbiting twin suns in multiplanetary system.

Astronomers have discovered a new circumbinary planet, BEBOP-1c, in a star system around 1,320 light-years from Earth, making it the 15th known Tatooine world. The discovery is further proof that these Star Wars-like planets are more common than scientists previously thought. The BEBOP-1 system is also a multi-planetary circumbinary system (MCS), with the previously known BEBOP-1b being around the same size as Saturn. The team will continue to study the BEBOP-1 system to learn more about how circumbinary planets form, and there is a chance that the system contains even more planets waiting to be detected.

Scientists find Tatooine-like planetary system using radial velocity data.

Astronomers have discovered a new planet, TOI-1338 c, in a Tatooine-like system that orbits two stars at once. The gas giant is approximately 65 times the mass of Earth and takes 215 days to orbit its sun. It's the second planet to be found in this faraway solar system, following the discovery of TOI-1338 b in 2019. Both orbit their star in the solar system, called TOI-1338, which is about 4.4 billion years old and located 1,300 light-years away from Earth, in the constellation Pictoris.
