An article published in the journal "Science" reports a study on the HD 148937 system, a binary system surrounded by a double nebula known as NGC 6164/6165. A team of researchers used the PIONIER and GRAVITY instruments and archival data from the FEROS instrument to collect the data necessary to conclude that it was originally at least a triple system and at some point two of the stars merged.
