Ko te wāhanga tuarua o te pūnaha i kitea hoki e Luhman i te tau 2013, ā, i panuitia i roto i te tuhinga kotahi me te tuatahi. I tangohia tōna whakaahua i te i-band i te pō o te 23 o Hui-tanguru 2013 ki te Gemini Multi-Object Spectrograph (GMOS) i te telescope Gemini South, Chile. I whakatauhia ngā wāhanga o te pūnaha ki te tawhiti koki o 1.5 arcseconds, e ōrite ana ki te wehenga e whakaarohia ana o 3 AU, me te rerekētanga nui o 0.45 mag. Pātai: He aha te tawhiti koki i kitea e ngā wāhanga o te pūnaha e Luhman i te tau 2013?
