Gallium Overabundance in the Ap-Si Star HD 25823
Published online by Cambridge University Press: 12 April 2016
Abstract
An anomalous enhancement of the resonance line of Ga II at 1414.44 Å is observed in IUE spectra of the silicon star HD 25823. High-resolution spectrum of this star is compared to synthetic spectra calculated in the range 1406–1422 Å. The LTE abundance of gallium is evaluated to log NGa = 6.3 ± 0.5 in the scale where log NH = 12.
