THE ULTRAVIOLET SPECTRUM OF 3 CENTAURI A
Journal Article
·
· Astrophysical Journal (U.S.)
A list of idenifications is given for 65 lines measured on a Radcliffe coude spectrogram of the region lambda lambda 31203700 in the spectrum of 3 Cen A (B4p). Lines of Mn II are present; the resonance Be II doublet lambda 3130 is absent. Relative abundance or upper limits for Be and the iron-peak elements are derived by comparison with alpha Lyr (AO V). The abundance ratio Mn: Fe is normal in 3 Cen A; that of Ni: Fe is a little low; the abundance of Be is less than, or equal to, that in alpha Lyr, while the abundance ratio Cr: Fe is lower than in 3 Cen A than in alpha Lyr by a factor of more than about 40. The possible relation between 3 Cen A and the magnetic peculiar A stars is discussed in the light of these new results. (auth)
