Far-Ultraviolet Spectroscopy of Low Mass X-ray Binaries with HST/COS
Abstract
We have obtained FUV spectroscopy of the X-ray binaries A0620-00, 4U0614+091, and MS1603.6+2600 using the Cosmic Origins Spectrograph on HST. The UV observations have been accompanied by contemporaneous multiwavelength X-ray, optical/NIR, and (for A0620-00) radio observations. The data provide constraints on the structure of the accretion disk and disk outflows, the evolutionary histories of the systems, and the physical properties of the accreting material. We will present the observations and analysis of the multiwavelength data.
