HD 129116 är en ensam stjärna^[10] belägen i den norra delen av stjärnbilden Kentauren som också har Bayer-beteckningen b Centauri. Den har en skenbar magnitud av ca 4,01^[2] och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 9,6^[1] mas, beräknas den befinna sig på ett avstånd på ca 339 ljusår (ca 104 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 2,5 km/s.^[2] Stjärnan ingår med 93 procent sannolikhet i rörelsegruppen Sco OB2.^[11]

Egenskaper redigera

HD 129116 är en blå till vit stjärna i huvudserien av spektralklass B3 V.^[3] Den har en massa som är ca 6,3^[5] solmassor, en radie som är ca 2,9^[6] solradier och har ca 637 gånger solens utstrålning av energi^[2] från dess fotosfär vid en effektiv temperatur av ca 18 400 K.^[6]

HD 129116 har använts som en "standardstjärna" i flera fotometriska system och verkar vara ickevariabel.^[4] Den är beräknad att vara 18^[5] miljoner år gammal och har snabb rotation med en beräknad rotationshastighet av 129 km/s.^[7]
