The chemical composition of HIP34407/HIP34426 and other twin-star comoving pairs
I. Ramirez, S. Khanal, S. J. Lichon +4
We conducted a high-precision elemental abundance analysis of the twin-star comoving pair HIP34407/HIP34426. With mean error of 0.013 dex in the differential abundances (D[X/H]), a…
