Supernova iPTF13bvn was spotted on June 16, less than a day after the onset of its explosion. With the aid of the adaptive optics system used by the 10-meter Keck telescopes in Hawaiiâ?”which reduces the blurring effects of Earth's atmosphereâ?”the team obtained a high-resolution image of this supernova to determine its precise position. Then they compared the Keck image to a series of pictures of the same galaxy (NGC 5806) taken by the Hubble Space Telescope in 2005, and found one starlike source spatially coincident to the supernova. Its intrinsic brightness, color, and sizeâ?”as well as its mass-loss history, inferred from supernova radio emissionsâ?”were characteristic of a Wolf-Rayet star.
