The solar niobium abundance

Abstract

The solar Nb abundance is derived from five Nb i and ten Nb ii lines in the photospheric spectrum. Equivalent widths are obtained from measurements on spectra recorded at Kitt Peak National Observatory. Synthetic spectrum calculations gave abundances of 2.23 and 2.08 from neutral and ionized lines respectively in the logarithmic AH = 12.00 scale. This gives an average abundance value of ANb = 2.13 ± 0.10.
