This thesis deals with observations, and subsequent analysis made of the high-mass X-ray binary systems Cen X-3 and Vela X-l. By making precise radial velocity measurements of the supergiant components, and combining these results with previous X-ray data, the masses of the neutron star components can be determined. The mass of the neutron star in Cen X-3 is found to be 1.21±0.21Mo, while the mass of the neutron star in Vela X-l is found to be 1.77+0.55-0.29M. The thesis concludes with an account of an attempt to detect radio emission from the Vela X-l bowshock.
