"Astronomers haven't yet determined the mass of TOI-1859 b, but they found that the planet's orbit is highly eccentric, or flattened, and misaligned in relation to its star. The strange orbit of this warm Jupiter could be the result of interactions with other planets in the planet's cosmic neighborhood, the team said in a paper accepted for publication in The Astrophysical Journal Letters and published in the preprint database arXiv."
My note. I periodically see reports on *misaligned* exoplanets.
This exoplanet orbits around its star's poles,

"...The researchers presented their work in a new paper to be published in the journal Astronomy and Astrophysics. It's titled "A puffy polar planet: The low-density, hot Jupiter TOI-640 b is on a polar orbit."..."In a 2021 paper titled "A Preponderance of Perpendicular Planets," the authors wrote that the "pile-up of polar orbits is a clue about the unknown processes of obliquity excitation and evolution."...Kozai Mechanism: These are interactions between a star and its planet and a third body called the perturber. It can affect inclination and eccentricity and can even flip planets into retrograde or prograde orbits."
The Gaia spacecraft is helping to fill the gaps in our understanding of "hot Jupiters," mysterious, massive planets that orbit very close to their stars. Mysterious 'hot Jupiter' planets can form quickly or slowly, Gaia spacecraft reveals : Read more

"Hot Jupiters with orbits misaligned from the equators of their stars are thought to form late relative to those that are aligned, like the planets in our solar system." Reference paper cited, Evidence for the Late Arrival of Hot Jupiters in Systems with High Host-star Obliquities, 29-April-2022,
