cds-question@unistra.frpeculiar-variable-starschemically-peculiar-starsWe have performed the abundance analysis of the cool magnetic CP star HR 8216 (=HD 204411) using 2.4{AA}/mm Dominion Astrophysical Observatory Reticon exposures covering ll 3830-4770{AA} with a typical signal-to-noise ratio of 200. The spectrograms were measured interactively with the graphics computer program REDUCE. We performed a fine analysis with an ATLAS9 metal-rich model atmosphere whose predictions best matched the optical region fluxes and the Hg profile. HR 8216's anomalies are primarily an enhancement of many iron peak elements with the rare earths elements much less enhanced than for many similar cool magnetic CP stars .Using the results of the fine analysis we synthetized the spectrum. Comparison with the observed spectrum showed that agreement is better.2005MNRAS.356.1256Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/356/1256CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/107/353 : CP stars (Lopez-Garcia+, 1994)J/A+AS/125/219 : Abundances of mu Lep, 7 Sex, HR 4817 + 28 Her (Adelman+ 1997)J/A+AS/129/563 : Abundances of HR 4487, 14 Hyd and 3 Cen A (Pintado+ 1998)J/A+A/354/899 : Elemental abundance analyses IV.
