Fig. 2: Abundance pattern of J1010+2358.
From: A metal-poor star with abundances from a pair-instability supernova
The red circles denote J1010+2358. The open symbols indicate four previously known metal-poor stars with sub-solar [Mg/Fe] ratios. The abundances of these α-poor metal-poor stars (−2.46 ≤ [Fe/H] ≤ −1.91) have been well studied on the basis of high-resolution spectroscopic analysis15,16. The shaded regions indicate abundances of other metal-poor stars from the literature10,11. The arrows represent the upper limits.
