The mid-ultraviolet spectrum of Epsilon Aurigae

An LTE synthetic spectrum with Te = 7800 K and log g = 1 has been computed for the 2455-to-3230 A range of Epsilon Aurigae (F0 1a). This has been compared with the spectra observed with 0.2 A resolution with the IUE experiment and with 0.1 A resolution with the BUSS experiment. As a consequence of this comparison, identifications and abundance values have been obtained. Ions definitely present include Mg I, Mg II, Al I, Al II, Si I, Ca II, Ti II, V II, Cr II, Mn II, Fe I, Fe II, Co II, Ni I, Ni II, Zr II. Ions which are possibly present include Ti III, Mn I, Fe III, Nb II, Mo I. The abundances are nearly 10 times the solar values for the iron group, with the exception of Fe, which has solar abundance. The abundances of the other elements are solar.
