Signatures of convection in the spectrum of Procyon: Fundamental parameters and iron abundance
Allende Prieto, Carlos; Asplund, Martin; Garcia Lopez, Ramon J; Lambert, David L
Description
We have observed the spectrum of Procyon A (F5 IV) from 4559 to 5780 Å with a signal-to-noise ratio of ~10[superscript 3] and a resolving power of 2×10[superscript 5]. We have measured the line bisectors and relative line shifts of a large number of Fe I and Fe II lines, comparing them to those found in the solar spectrum. A three-dimensional hydrodynamical model atmosphere has been computed and is tested against observations. The model reproduces in detail most of the features observed,...[Show more]
