Differential abundance analysis of Procyon and Theta Sculptoris: Comparison with abundance patterns of solar-like pairs

C. R. Cowley, K. Yüce, D. J. Bord

The precision differential abundance (PDA) technique is applied to the mid-F stars Procyon and $\theta$ Scl using spectra from the ESO UVESPOP library. We relate PDA patterns to endogen…
