Description
High mass X-ray binaries (HMXBs) are important laboratories where to
study the characteristics of the accretion processes and the nature of
compact objects. For this reason, we have started the determination of
the fundamental properties (mass, radius, temperature, etc.) of the
optical components in four systems: 2S 0114+65, IGR J00370+6122, XTE
J1855-026 and 2XMM J205347.0+442301. The dynamical analysis of the
optical component, together with the observed characteristics in X-rays,
allows the determination of the fundamental properties of the compact
object (e.g. the mass, the accretion rate, etc.). For the studied
systems, we have determined preliminary orbital solutions using radial
velocities from the INT, the WHT, the Liverpool telescope and the
Mercator telescope. The obtained results provide a first insight into a
wide range of accretion processes and different compact objects in each
one of the studied systems.
