GHRS Observations of the Bp Star, chi Lupi
Published online by Cambridge University Press: 30 March 2016
Abstract
High resolution, high S/N ultraviolet observations of the ultra-sharp-lined Bp star chi Lupi, obtained with the Goddard High Resolution Spectrograph, reveal an unprecedented level of spectroscopic detail. Spectral synthesis of the Hg II λ1942 resonance line confirms the extreme isotope abundance anomaly of mercury in this star. The data also provide the first positive detections of Ru II and Zr III, and tentative detections of As I and Ge II.
