Query: A study of accretion discs around rapidly rotating neutron stars in
  general relativity and its applications to four Low Mass X-ray Binaries   We calculate the accretion disc temperature profiles, disc luminosities and
boundary layer luminosities for rapidly rotating neutron stars considering the
full effect of general relativity. We compare the theoretical values of these
quantities with their values inferred from EXOSAT data for four low mass X-ray
binary sources: XB 1820-30, GX 17+2, GX 9+1 and GX 349+2 and constrain the
values of several properties of these sources. According to our calculations,
the neutron stars in GX 9+1 and GX 349+2 are rapidly rotating and stiffer
equations of state are unfavoured.
