Scientific paper

Results are reported of spectroscopy of the B-star primary of the X-ray binary 1E1145-6141 obtained during the past five years. Since the period is longer than the individual observing runs, it is difficult to determine unambiguously, but the most probable orbital period is 10.756 days. A less likely possibility is 12.09 days. The orbital parameters are derived and used to show that the system contains a neutron star of mass 1.4 to 2.0 solar masses and a B2 supergiant of mass 10 to 18 solar masses. The orbital inclination is 45-65 deg, the mass ratio is 6-9, and the primary is undermassive for its type and luminosity.
