X-ray Observations of Bow Shocks around Runaway O Stars. The case of Oph and BD+433654
J. A. Toalá, L. M. Oskinova, A. González-Galán +3
Non-thermal radiation has been predicted within bow shocks around runaway stars by recent theoretical works. We present X-ray observations towards the runaway stars Oph (Chandr…
The donor star of the X-ray pulsar X1908+075
Silvia Martínez-Núñez, Andreas Sander, Ángel Gímenez-García +4
High-mass X-ray binaries (HMXBs) consist of a massive donor star and a compact object. While several of those systems have been well studied in X-rays, little is known for most of…
Fundamental properties of High-Mass X-ray Binaries
A. González-Galán
The aim of this PhD Thesis is to characterize a representative sample of Supergiant X-ray Binaries (SGXBs) formed by 4 sources: XTE J1855-026, a classical SGXB with long-term stabl…
Astrophysical parameters and orbital solution of the peculiar X-ray transient IGR J00370+6122
A. González-Galán, I. Negueruela, N. Castro +3
BD+6073 is the optical counterpart of the X-ray source IGR J00370+6122, a probable accretion-powered X-ray pulsar. The X-ray light curve of this binary system shows clear periodici…
Spin period evolution of the X-ray pulsar GX 1+4
A. González-Galán, E. Kuulkers, P. Kretschmar +4
We report on the long-term evolution of the spin period of the symbiotic X-ray pulsar GX 1+4 and a possible interpretation within a model of quasi-spherical accretion. New period m…
Wind accretion in symbiotic X-ray binaries
K. Postnov, N. Shakura, A. González-Galán +7
The properties of wind accretion in symbiotic X-ray binaries (SyXBs) consisting of red-giant and magnetized neutron star (NS) are discussed. The spin-up/spin-down torques applied t…
