LkCa 15 b or Lick-Calcium 15b[citation needed] is a candidate protoplanetary object in orbit around LkCa 15, a star in the Taurus-Auriga Star Forming Region. It was discovered by direct imaging techniques using the Keck II telescope in 2011 by Adam Kraus and Michael Ireland.[1] A 2015 study of observations from the Magellan Telescopes and the Large Binocular Telescope argued that the planet is forming though accretion.[2] It is the first observed exoplanet seen in the process of active accretion.[3]
