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] References1. ^1 2 {{cite journal|title=LkCa 15: A Young Exoplanet Caught at Formation?|last1=Kraus|first1=Adam L.|last2=Ireland|first2=Michael J.|date=2011|journal=The Astrophysical Journal|volume=745|issue=1|doi=10.1088/0004-637X/745/1/5|arxiv=1110.3808|bibcode = 2012ApJ...745....5K|page=5}} 2. ^{{cite journal|last1=Sallum|first1=S.|last2=Follette|first2=K.
