BEBOP-1c is the newly discovered planet, while the first one in this system is TOI-1338b.
Record-breaking: Astronomers detect heaviest element ever found on exoplanet 556 light years from EarthThe two planets orbit the pair of stars at once. The newly discovered exoplanet is named after the BEBOP program.The team discovered this new exoplanet by chance while studying the circumbinary system's first known planet .“The transit method permitted us to measure the size of TOI-1338b, but not its mass which is the planet’s most fundamental parameter,” said Dr.
The BEBOP team continued to investigate this system by employing a technique known as the Doppler method, which measures the velocity of stars. The researchers utilized two telescopes in Chile's Atacama Desert to determine the mass of TOI-1338b. Despite years of effort, the BEBOP team was unable to precisely determine the mass of TOI-1338b.
However, their efforts were rewarded in a different way when they discovered a second planet in the same system. And, fortunately, they were able to determine the mass of BEBOP-1c. “BEBOP-1c has an orbital period of 215 days, and a mass 65 times larger than Earth, which is about five times less than Jupiter’s mass,” said Dr Standing.
Only two exoplanets are known to exist in this circumbinary system at present, but scientists predict that there may be others waiting to be discovered.The study has been published in the journalCircumbinary planets, those that orbit around both stars of a central binary star system, challenge our understanding of planet formation.
