U Antliae --- A Dying Carbon Star
Abstract
U Antliae is one of the brightest carbon stars in the southern sky. It is classified as an N0 carbon star and an Lb irregular variable. This star has a very unique spectrum and is thought to be in a transition stage from an asymptotic giant branch star to a planetary nebula. This paper discusses possible atomic and molecular line identifications for features seen in high-dispersion spectra of this star at wavelengths from 4975 Å through 8780 Å.
