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.…
A photometric redshift of for the \agile GRB 080514B
A. Rossi, A. de Ugarte Postigo, P. Ferrero +26
Aims: The AGILE gamma-ray burst GRB 080514B is the first burst with detected emission above 30 MeV and an optical afterglow. However, no spectroscopic redshift for this burst is kn…
Unveiling the nature of six HMXBs through IR spectroscopy
E. Nespoli, J. Fabregat, R. E. Mennickent
The International Gamma-Ray Astrophyiscs Laboratory (INTEGRAL) is discovering a large number of new hard X-ray sources, many of them being HMXBs. The identification and spectral ch…
A photometric study of Be stars located in the seismology fields of COROT
J. Gutierrez-Soto, J. Fabregat, J. Suso +4
Context: In preparation for the COROT mission, an exhaustive photometric study of Be stars located in the seismology fields of the COROT mission has been performed. The very precis…
