▪ Abstract The Goddard High-Resolution Spectrograph (GHRS) aboard the Hubble Space
Telescope (HST) has yielded precision abundance results for a range of interstellar …

ABSTRACT Using the Goddard High Resolution Spectrograph (GHRS) onboard the Hubble
Space Telescope, we have obtained high signal-to-noise (S/N) ratio echelle observations of …

We report new observations of Zn II and Cr II absorption lines in 10 damped Ly α systems
(DLAs), mostly at redshift z abs ≳ 2.5. By combining these results with those from our …

We present a comprehensive analysis of the damped Ly α (DLA) abundance database
presented in the first paper of this series. This database provides a homogeneous set of …

We present HST spectra for a sample of six QSOs with intermediate redshift (z_a< 1)
damped Ly-alpha systems. These observations aim at measuring the HI column density and …

Spectra obtained with the Hubble Space Telescope Goddard High Resolution Spectrograph
are combined with high-resolution optical spectra and UV spectra from Copernicus to study …

In this paper we continue our investigation of diffuse clouds in the interstellar medium with
an analysis of the line of sight toward the star HD 215733, located in the Galactic halo some …

Type I planetary nebulae (PNe) have high He/H and N/O ratios and are thought to be
descendants of stars with initial masses of∼ 3–8 M☉. These characteristics indicate that the …

We present a study of the composition of gas and dust in the Large and Small Magellanic
Clouds (LMC and SMC) using UV absorption spectroscopy. We measure P ii and Fe ii along …

We present high-resolution, high signal-to-noise ratio spectra of the QSO Q2206-199
obtained with HIRES on the 10 m WM Keck Telescope. Our analysis focuses on the two …
