LkCa 15 is a T Tauri star in the Taurus Molecular Cloud.

LkCa 15 is surrounded by a protoplanetary disk, typical of many T Tauri stars.

[7] The disk around the star is about 55 times more massive than Jupiter,[8] and consists of three major belts (components).

[4] Small changes in the observed brightness of the disk may be due to a planetary companion; the star was believed to have a protoplanetary object or exoplanet orbiting it, known as LkCa 15 b[9][10] This name stems from an older survey.

Its potential discovery was effected by direct imaging techniques using the Keck II telescope in 2011 by Adam Kraus and Michael Ireland.
