LkCa 15 b 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. A 2015 study of observations from the Magellan Telescopes and the Large Binocular Telescope argued that the planet is forming through accretion. It is the first observed exoplanet seen in the process of active accretion. The planet existence was refuted in 2019 as higher resolution imaging has become available.
