dc.description.abstractAn elemental abundance analysis of the cool magnetic CP star HR 8216 (= HD204411) was performed using 2.4 Angstrom mm(-1) Dominion Astrophysical Observatory Reticon exposures covering lambdalambda3830-4770 with a typical signal-to-noise ratio of 200 taken with the long camera of the 1.22-m telescope. The spectrograms were measured interactively with the graphics computer program REDUCE. The fine analysis used an ATLAS9 metal-rich model atmosphere, the predictions of which best-matched the optical region fluxes and the Hgamma profile. The anomalies of HR 8216 are primarily an enhancement of many iron peak elements with the rare earths elements much less enhanced than in many similar cool magnetic CP stars. Using the results of the fine analysis the spectrum was synthesized. Comparison with the observed spectrum showed that the agreement is good but did not fully account for all of the observed line spectrum.
