Bizarre Exoplanet Breaks All the Orbital Rules - by BrianKoberlein
The planet was discovered via the transit method, which means it passes in front of its star from our point of view. It’s an effective way to find exoplanets, but it can also be used to verify the rotational motion of the star. Because of stellar rotation, light coming from the region of the star rotating toward us is slightly blueshifted, and light from the region rotating away from us is slightly redshifted. This means that spectral lines from the star are blurred a bit.
One idea is a process known as the Kozai effect. Dynamical interactions between the planet, its star, and other planets in the system can cause the orbit to shift away from the invariant planet. We see this in our own solar system with Pluto and Neptune, which has tilted Pluto’s orbit over time. The Kozai effect is more pronounced with smaller planets, however, and interaction between planet and star alone isn’t enough to explain such an inclined orbit.
Although the mechanism behind the odd orbit isn’t clear, it does follow a pattern seen with many hot gas exoplanets. About a quarter of them have significantly tilted orbits. It seems that these planets sometimes get way out of line.
