Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: Ko te waahanga tuarua o te punaha i kitea ano e Luhman i te tau 2013, a i panuitia i roto i te tuhinga kotahi me te tuatahi. Ko tōna kitenga i roto i te i-band i tangohia i te po o te 23 o Hui-tanguru 2013 me te Gemini Multi-Object Spectrograph (GMOS) i te telescope Gemini South, Chile. I whakatauhia nga waahanga o te punaha me te tawhiti koki 1.5 arcseconds, e pa ana ki te wehenga e whakaarohia ana mo te 3 AU, me te rereketanga nui o te 0.45 mag.  Pātai: He aha te tawhiti koki o ngā wāhanga o tētahi pūnaha i kitea e Luhman i te tau 2013?
