The following paper suggests the existence of a A circumbinary planet on a polar orbit, the first of its kind, using RV data:
Evidence for a polar circumbinary exoplanet orbiting a pair of eclipsing brown dwarfs, (ESO press release)
Abstract:
One notable example of exoplanet diversity is the population of circumbinary planets, which orbit around both stars of a binary star system. There are so far only 16 known circumbinary exoplanets, all of which lie in the same orbital plane as the host binary. Suggestions exist that circumbinary planets could also exist on orbits highly inclined to the binary, close to 90 ∘
, polar orbits. No such planets have been found yet but polar circumbinary gas and debris discs have been observed and if these were to form planets then those would be left on a polar orbit. We report strong evidence for a polar circumbinary exoplanet, which orbits a close pair of brown dwarfs which are on an eccentric orbit. We use radial-velocities to measure a retrograde apsidal precession for the binary, and show that this can only be attributed to the presence of a polar planet.
The system is 2MASS J15104786-2818174, or TIC 61253912
The discovery of the eclipsing brown dwarf system (with an outer non-eclipsing companion as well) itself was in the 2020 paper by Triaud et al..
