World First: Interior Rotation Of A Star Seen, Planet Almost Twice As Large As Jupiter Found

With the help of asteroseismic data obtained by the CoRoT space telescope, scientists were able to determine the interior rotation of a Sun-like star – and characterise an exoplanet. A team of scientists led by researchers from the Max Planck Institute for Solar System Research (Germany) and the University of Göttingen (Germany) have for the first time unambiguously measured the internal rotation of a Sun-like star and determined the inclination of its rotation axis. Their calculations show that the star rotates about 2.3 times faster than the Sun, with the axis of rotation inclined at 30 degrees to our line of sight. The star, HD52265, is located more than 90 light years away in the constellation of Monoceros.
