Query: The Relativistic Fe Emission Line in XTE J1650-500 with BeppoSAX:
  Evidence for Black Hole Spin and Light Bending Effects?   We report spectral results from three BeppoSAX observations of the black hole
candidate XTE J1650-500 during its 2001/2002 outburst. We find strong evidence
for the presence of a broad and strongly relativistic Fe emission line. The
line profile indicates an accretion disc extending down to two gravitational
radii (or less) suggesting the presence of a rapidly rotating central Kerr
black hole. Thanks to the broadband spectral coverage of BeppoSAX, we could
analyze the 1.5-200 keV spectra of the three observations and report the
presence of a strong reflection component from the accretion disc, which is
totally consistent with the observed broad Fe emission line. The shape of the
reflection component appears to be affected by the same special and general
relativistic effects that produce the broad Fe line. We study the variation of
the different spectral components from the first to the third observation and
we find that they are well reproduced by a recently proposed light bending
model.
