Revisiting the Interstellar Abundances Toward X Per
Abstract
The nearby X-ray binary X Per (HD 24534) is a useful beacon with which to measure elemental abundances in the local ISM and examine possible dust constituents. Spectra were obtained from Chandra Observatory's LETG/ACIS-S and XMM-Newton's RGS instruments. The absorption features of O, Mg, Si, and Fe were examined and column densities were found. The abundances are similar to those of commonly-used abundance references. Further, MgSiO3 may be a significant absorber at the O, Si, and Mg K edges, while metallic iron and oxides may contribute to absorption at the Fe L edge.
