Stellar chemical abundances with the GHRS

Research output: Contribution to journalArticle

Abstract

The accurate quantitative analysis of high resolution ultraviolet spectra of ultra-sharp-lined early-type, chemically peculiar stars, obtained with the Goddard High Resolution spectrograph on the Hubble Space Telescope, has been made possible by the synergism between state-of-the-art astro-physics and state-of-the-art atomic spectroscopy. We illustrate this with several examples, including the discovery of spin-forbidden ''parasite'' transitions of Fe II, the first observations of hyperfine components and isotopic shifts of stellar lines of thallium, and measurements of the photospheric abundances of a large number of normally trace elements.
