Abstract

The solar chemical abundances studied in considerable detail because of discrepant values of solar metallicity inferred from different indicators, where in the present work we have used 28 suitable atomic spectral solar nitrogen lines, relying on new equivalent widths measurements for determining the nitrogen abundance. Corresponding to 28 solar neutral nitrogen lines, we derived a solar abundance of nitrogen using the Holweger and Müller (1974) solar model and the measured equivalent widths from the literature. Our study reported the solar nitrogen abundance result to be of 8.05±0.09 using gƒ-values from Wiese and Fuhr (2007).
