Pulsing Stars Reveal Orbiting Planets –“The Link Is a Mystery That Can’t Be Explained”

For the first time, astronomers from MIT and elsewhere have observed a star pulsing in response to its orbiting planet. The star, which goes by the name HAT-P-2, is about 400 light years from Earth and is circled by a gas giant measuring eight times the mass of Jupiter—one of the most massive exoplanets known today.

The precisely timed pulsations have lead the researchers to believe that, contrary to most theoretical model-based predictions of exoplanetary behavior, HAT-P-2b may be massive enough to periodically distort its star, making the star’s molten surface flare, or pulse, in response.
