Of the 14 transiting planets that have been detected orbiting eclipsing binaries (‘circumbinary planets’), none have been detected with stellar binary orbital periods shorter than 7 days, despite such binaries […]

Photo-dynamical Analysis of Circumbinary Multi-planet System TOI-1338: a Fully Coplanar Configuration with a Puffy Planet
TOI-1338 is the first circumbinary planet system discovered by TESS. It has one transiting planet at P∼95 day and an outer non-transiting planet at P∼215 day complemented by RV observation.

Inclination Instability Of Circumbinary Planets
We analyze a tilt instability of the orbit of an outer planet in a two planet circumbinary system that we recently reported.

The Search For More Temperate Tatooines
Luke Skywalker’s childhood might have been slightly less harsh if he’d grown up on a more temperate Tatooine — like the ones identified in a new, Yale-led study.
![Phase-folded light curve of EBLM J0608−59 (TOI-1338, BEBOP-1) from the WASP project. The data in blue are phase-binned and offset vertically to make the transit at phase 0 easier to see in this automatically-generated diagnostic plot. This system was first flagged as an EBLM system by Amaury Triaud on 2010-07-02 based on follow-up radial velocity meausurements obtained with the CORALIE spectrograph on the Swiss Euler 1.2-m telescope. This binary would later be discovered to host two circumbinary planets, one identified from a transit observed in the TESS light curve [7] and the other long-period planet identified from radial-velocity measurements obtained by the BEBOP project [8]. -- astro-ph.SR](https://i0.wp.com/astrobiology.com/wp-content/uploads/2023/11/TheEBLMProject.png?resize=1200%2C718&ssl=1)

The EBLM Project — From False Positives to Benchmark Stars and Circumbinary Exoplanet
The EBLM project aims to characterise very low-mass stars that are companions to solar-type stars in eclipsing binaries. We describe the history and motivation for this project, the methodology we […]

Statistics of Magrathea Exoplanets Beyond The Main Sequence. Simulating The Long-term Evolution Of Circumbinary Giant Planets With TRES
Notwithstanding the tremendous growth of the exoplanetary field in the last decade, limited attention has been paid to the planets around binary stars. Circumbinary planets (CBPs) have been discovered primarily […]
