CPD−57°2874 is a [[B(e) star|B[e] supergiant]] in the constellation Carina. It is a rare star as it is hot but has dust which shows forbidden lines and IR emissions. In 2007 the high spatial and spectral resolution of the star's circumstellar envelope was studied. This was the first time such a study was carried out on a class B[e] supergiant.
