Determination of the mass of the neutron star in SMC X-1, LMC X-4 and Cen X-3 with VLT/UVES
A. van der Meer, L. Kaper, M. H. van Kerkwijk +2
We present the results of a spectroscopic monitoring campaign of the OB-star companions to the eclipsing X-ray pulsars SMC X-1, LMC X-4 and Cen X-3. High-resolution optical spectra…
VLT/UVES spectroscopy of Wray 977, the hypergiant companion to the X-ray pulsar GX301-2
L. Kaper, A. van der Meer, F. Najarro
Model atmosphere fits to high-resolution optical spectra of Wray 977 confirm the B hypergiant classification of the massive companion to the X-ray pulsar GX301-2. The models give a…
Massive Stars and their Compact Remnants in High-mass X-ray Binaries
L. Kaper, A. van der Meer
In a high-mass X-ray binary (HMXB) a massive star interacts with a neutron-star or black-hole companion in various ways. The gravitational interaction enables the measurement of fu…
On the mass distribution of neutron stars in HMXBs
A. van der Meer, L. Kaper, M. H. van Kerkwijk +1
We present the results of a monitoring campaign of three eclipsing high-mass X-ray binaries (HMXBs: SMC X-1, LMC X-4 and Cen X-3). High-resolution VLT/UVES spectra are used to meas…
XMM-Newton X-ray spectroscopy of the high-mass X-ray binary 4U1700-37 at low flux
A. van der Meer, L. Kaper, T. Di Salvo +4
We present results of a monitoring campaign of the high-mass X-ray binary system 4U 1700-37/HD 153919, carried out with XMM-Newton in February 2001. The system was observed at four…
