New planet found to affect its star's rotation
An international team of astronomers has discovered a giant exoplanet 2,100 light-years away, named HATS-18b, whose gravity might be influencing its parent star's rotation. The planet has an orbital period of 0.84 earth days. "The high planet mass, combined with its short orbital period, implies strong tidal coupling between the planetary orbit and the star", the paper read.
