A fine analysis performed using four 4.3 Å/mm IIaO Mt. Wilson Observatory spectrograms shows that HD 43819 has abundance anomalies similar to those of other Silicon stars, namely it is helium, carbon, magnesium, and sulfur poor while being silicon, titanium, chromium, manganese, iron, strontium, zirconium, and rare earth rich.
