Elemental Abundances In The Diffuse ISM From Joint FUV and X-ray Spectroscopy: Iron, Oxygen, Carbon and Sulfur
In this study, we investigate interstellar absorption lines along the line of sight toward the galactic low-mass X-ray binary Cygnus X-2. We combine absorption line data obtained from high-resolution X-ray […]
