Discovery of slow X-ray pulsations in the high-mass X-ray binary 4U 2206+54

P. Reig, J. M Torrejon, I. Negueruela +3

The source 4U 2206+54 is one of the most enigmatic high-mass X-ray binaries. In spite of intensive searches, X-ray pulsations have not been detected in the time range 0.001-1000 s.…

Rapid spectral and timing variability of Be/X-ray binaries during type II outbursts

P. Reig

We have investigated the spectral and timing variability of four accreting X-ray pulsars with Be-type companions during major X-ray outbursts. Different spectral states were define…

The very massive X-ray bright binary system Wack 2134 (= WR 21a)

V. S. Niemela, R. C. Gamen, R. H. Barba +5

From the radial velocities of the N IV 4058 and He II 4686 emission lines, and the N V 4604-20 absorption lines, determined in digital spectra, we report the discovery that the X-r…

Fourier resolved spectroscopy of 4U 1728-34: New Insights into Spectral and Temporal Properties of Low-Mass X-ray Binaries

C. R. Shrader, P. Reig, D. Kazanas

Using archival RXTE data we derive the 2-16 keV Fourier-resolved spectra of the Atoll source 4U 1728-34 in a sequence of its timing states as its low QPO frequency spans the range…

On the neutron star-disc interaction in Be/X-ray binaries

P. Reig

We have investigated the long-term X-ray variability, defined as the root-mean-square (rms) of the ASM RXTE light curves, of a set of galactic Be/X-ray binaries and searched for co…

Fourier resolved spectroscopy of 4U 1543-47 during the 2002 outburst

P. Reig, I. E. Papadakis, C. R. Shrader +1

We have obtained Fourier-resolved spectra of the black-hole binary 4U 1543-47 in the canonical states (high/soft, very high, intermediate and low/hard) observed in this source duri…
