Star Rips Exoplanet to Shreds with X-Rays

astroengine writes "Some relationships are doomed from the beginning, and the same can be said of some planetary systems. In the case of the star CoRoT-2a, some 880 light-years from Earth, it is quite literally ripping its orbiting exoplanet to shreds. Five million tons of material per second is being stripped from the closely orbiting world CoRoT-2b by powerful stellar X-rays. But it's OK, the destructive nature of this planetary system is mutual; CoRoT-2b's orbit is likely maintaining the high spin rate of the star, boosting magnetic activity, thus boosting the X-ray output. This is one relationship that can only end in tears."
