Abstract: |
Here I present an overview of the Bowen survey of
low mass X-ray binaries (LMXBs). The Bowen fluorescence technique uses
the fact that narrow emission lines arise on the surface of the
irradiated donor of LMXBs, making possible to derive a radial
velocity curve and thereby constrain the mass of the compact object. I
will concentrate on the main results of the last ≃4 years, and
provide an example that illustrates the validity of the technique
(EXO 0748–676). Furthermore I will also illustrate where the
results were limited (SAX J1808.4–3658) or did not work. Finally,
now that the Bowen fluorescence technique has been applied to most of
the optically bright X-ray binaries I will point out several new
paths to pursue in the future. |
