The masses of the neutron and donor star in the high mass X-ray binary IGR J18027-2016
A. B. Mason, A. J. Norton, J. S. Clark +2
We report near-infrared observations of the supergiant donor to the eclipsing high mass X-ray binary pulsar IGR J18027-2016. We aim to determine its spectral type and measure its r…
The evolution and masses of the neutron star and donor star in the high mass X-ray binary OAO 1657-415
A. B. Mason, J. S. Clark, A. J. Norton +5
We report near-infrared radial velocity measurements of the recently identified donor star in the high mass X-ray binary system OAO 1657-415 obtained in the H band using ISAAC on t…
Preliminary determinations of the masses of the neutron star and mass donor in the High Mass X-ray Binary system EXO 1722-363
A. B. Mason, A. J. Norton, J. S. Clark +2
We intended to measure the radial velocity curve of the supergiant companion to the eclipsing high mass X-ray binary pulsar EXO1722-363 and hence determine the stellar masses of th…
Spectral classification of the mass donors in the high-mass X-ray binaries EXO 1722-363 and OAO 1657-415
A. B. Mason, J. S. Clark, A. J. Norton +2
We report near-infrared observations of the mass donors of the eclipsing high-mass X-ray binary (HMXB) systems EXO 1722-363 and OAO 1657-415 in order to derive their accurate spect…
