The solar manganese abundance

Abstract

A preliminary solar Mn abundance of logN(Mn) = 5.41 (logN(H) = 12.00) is derived on the basis of fitting theoretical line profiles which include hyperfine structure (HFS) broadening to the profiles of the λλ 5394.7, 5432.6, and 5537.8 lines of Mn observed at the center of the solar disk with the double-pass spectrograph of the McMath solar telescope at Kitt Peak. Both the Mn abundance and the collisional damping constant were varied during the fitting procedure in order to minimize the rms deviation between the observed and computed profiles.
