Fig. 3: Bulk titanium and oxygen isotopic compositions of Bennu samples (OREX-803015-100 and OREX-803015-101) in relation to other astromaterials.
From: The variety and origin of materials accreted by Bennu’s parent asteroid
a, Bulk ɛ50Ti versus oxygen isotopic composition. b, Bulk ɛ50Ti versus ɛ46Ti isotopic composition. CB, Bencubbin-like CCs; OC, ordinary chondrites; RC, Rumuruti chondrites; EC, enstatite chondrites; Aub, aubrites; Win, winonaites; Ang, angrites; HED/Mes, howardite–eucrite–diogenite and mesosiderite; Aca/Lod, acapulcoite and lodranite; Urei, ureilite. See Methods for sources of non-Bennu data. The symbols at the centre of ovals represent the centre of the range of values. The sizes of the ovals represent the range of data for each material, including reported 2 s.d. uncertainty on measurements.
