Descripción
The influence of gravitational microlensing on the X-ray spectral line
profiles originated from a relativistic accretion disc has been studied.
Using a disc model, we show that microlensing can induce noticeable
changes in the line shapes when the Einstein ring radius associated with
the microlens is of a size comparable to that of the accretion disc.
Taking into account the relatively small size of the X-ray accretion
disc, we found that compact objects (of about a Solar mass) which belong
to the bulge of the host galaxy can produce significant changes in the
X-ray line profile of AGN.
