The supergiant η Leo (A0 Ib)
Abstract
In this study we use preliminary atmospheric parameters for the A0 Ib supergiant η Leo (Teff, log g and microturbulent velocity) to provide initial estimates of the elemental abundances from S II, Ti II, Cr II, Fe I and Fe II lines by using spectrograms with a two pixel resolution of 0.072 Å and signal-to-noise ratio ≥ 200 taken at the Dominion Astrophysical Observatory.
