Bowen blend echo-tomography of low mass X-ray binaries
T. Muñoz-Darias, I. G. Martinez-Pais, J. Casares +7
We present simultaneous high time resolution (1-10 Hz) X-ray and optical observations of the persistent LMXBs Sco X-1 and V801 Ara(=4U 1636-536). In the case of Sco X-1 we find tha…
Echoes from the companion star in Sco X-1
T. Muñoz-Darias, I. G. Martinez-Pais, J. Casares +5
We present simultaneous X-ray (RXTE) and optical (ULTRACAM) narrow band (Bowen blend/HeII and nearby continuum) observations of Sco X-1 at 2-10 Hz time resolution. We find that the…
Optical polarimetric observations of the microquasar LS 5039
J. A. Combi, S. A. Cellone, J. Marti +3
We present the first optical polarimetric observations of the runaway microquasar LS 5039. Our results reveal the presence of a large amount (~5%) of polarized emission towards thi…
Bowen Fluorescence from Companion Stars in X-ray Binaries
J. Casares, D. Steeghs, R. I. Hynes +3
This paper will review a new technique of detecting companion stars in LMXBs and X-ray transients in outburst using the Bowen fluorescence lines at 4634-4640 Angs. These lines are…
Optical spectroscopy of microquasar candidates at low galactic latitudes
J. Marti, J. M. Paredes, J. S. Bloom +3
We report optical spectroscopic observations of a sample of 6 low-galactic latitude microquasar candidates selected by cross-identification of X-ray and radio point source catalogs…
Detection of variable circular polarization in the SW Sex star V795 Herculis
P. Rodriguez-Gil, J. Casares, I. G. Martinez-Pais +1
We report the detection of modulated circular polarization in V795 Her. The degree of polarization increases with wavelength and is modulated with a period of 19.54 min, which is v…
