In space, found a perfect sphere
In space, found a perfect sphere A group of astrophysicists led by Laurent Gizona (Laurent Gizon) of the max Planck Institute in Germany have discovered the most round object known in the Universe. He was a star KIC 11145123 located about five thousand light-years from Earth. Briefly about the discovery tells Gizmodo. See alsoDetected the brightest “alien” signal It is known that most stars (and planets) are not perfectly spherical, as they are flattened due to rotation around the axis, and the actions of its own poloidal (passing through the poles) magnetic fields. To determine the shape of space objects scientists have typically used optical interferometry, but its low resolution made it possible to study only close to the Solar system a rapidly rotating star. In the current study turned to astrophysics astroseismology method. Using the data obtained by the Kepler telescope, they measured the frequency of the periodic pulsations
