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.…
Very peculiar wind from BD+53 2790, the optical counterpart to 4U 2206+54
P. Blay, M. Ribó, I. Negueruela
BD+53 2790, an O9.5Vp star, is the optical counterpart to the HMXRB 4U 2206+54. This system was classified initially as a BeX, but observational evidence soon stressed the need to…
INTEGRAL long-term monitoring of the Supergiant Fast X-ray Transient XTE J1739-302
P. Blay, S. Martínez-Núñez, I. Negueruela +6
In the past few years, a new class of High Mass X-Ray Binaries (HMXRB) has been claimed to exist, the Supergiant Fast X-ray Transients (SFXT). These are X-ray binary systems with a…
Wind accretion in the massive X-ray binary 4U 2206+54: abnormally slow wind and a moderately eccentric orbit
M. Ribo, I. Negueruela, P. Blay +2
Massive X-ray binaries are usually classified depending on the properties of the donor star in classical, supergiant and Be X-ray binaries. The massive X-ray binary 4U 2206+54 does…
Multiwavelength monitoring of BD+53 2790, the optical counterpart to 4U~2206+54
P. Blay, I. Negueruela, P. Reig +4
We present the results of our long-term monitoring of BD+53 2790, the optical counterpart to the X-ray source 4U~2206+54. Unlike previous studies that classify the source as a Be/X…
INTEGRAL observations of the Be/X-ray binary EXO 2030+375 during outburst
A. Camero Arranz, C. A. Wilson, P. Connell +4
We present a type-I outburst of the high-mass X-ray binary EXO 2030+375, detected during INTEGRAL's Performance and Verification Phase in December 2002 (on-source time about 10e+06…
