TESS: A Trailblazer in Exoplanet Discovery
NASA’s Transiting Exoplanet Survey Satellite (TESS) has been instrumental in detecting exoplanets, with 885 confirmed discoveries and over 7,900 candidates identified so far. TESS has exceeded expectations, but one challenge remains—detecting planets in binary star systems.
The Challenge of Binary Star Systems
Binary star systems present a unique challenge for exoplanet detection using the transit method that TESS primarily employs. The complex interplay of gravity and light between the two stars makes it difficult to pinpoint planets’ transit signals.
Introducing a New Method: Apsis Precession
A team of astronomers led by Margo Thornton from the University of New South Wales has developed a new method to detect exoplanets in binary star systems. This method, called apsis precession, focuses on the gravitational effects of an exoplanet on the binary stars’ orbit, rather than relying on transit signals.

Unveiling Hidden Worlds: 27 New Potential Exoplanets
By applying this new method to TESS data, the research team identified 27 new potential exoplanets in binary star systems. These candidates have not yet been confirmed, but they represent a significant advancement in our understanding of exoplanets in binary systems.
The Future of Exoplanet Detection in Binary Star Systems
The discovery of these 27 potential exoplanets using apsis precession opens up new avenues for detecting planets in binary star systems. As TESS continues to gather data, and other missions like PLATO and Ariel join the search, we can expect many more exciting discoveries in the years to come.
Did you know?
- The first exoplanet discovered around a binary star system was Kepler-16b, a circumbinary planet orbiting two Sun-like stars.
- Binary star systems are more common in our galaxy than single-star systems, making up about half of all stellar systems.

FAQ:
Q: What is the smallest potential exoplanet discovered using this new method?
A: The smallest potential exoplanet discovered using apsis precession has an estimated minimum mass of 12 times that of Earth.
Q: How does the new method differ from the transit method used by TESS?
A: Unlike the transit method, which relies on detecting a planet’s passage in front of its star, apsis precession focuses on the gravitational effects of an exoplanet on the binary stars’ orbit, allowing for the detection of planets that may not be easily visible through transits.
