Kinematical Studies of the Low Mass X-Ray Binary GR Mus (XB1254-690)
A. D. Barnes, J. Casares, R. Cornelisse +4
We present simultaneous high-resolution optical spectroscopy and X-ray data of the X-ray binary system GR Mus (XB1254-690), obtained over a full range of orbital phases. The X-ray…
Optical spectroscopy of the low mass X-ray binary GX9+9
R. Cornelisse, D. Steeghs, J. Casares +4
Phase-resolved medium resolution VLT spectroscopy of the low mass X-ray binary GX9+9 has revealed narrow CIII emission lines that move in phase relative to our new estimate of the…
The isotopic 6Li/7Li ratio in Cen X-4 and the origin of Li in X-ray binaries
J. Casares, P. Bonifacio, J. I. Gonzalez Hernandez +2
Context: Cool stars, companions to compact objects, are known to show Li abundances which are high compared to field stars of the same spectral type, which are heavily Li depleted.…
SW Sextantis stars: the dominant population of CVs with orbital periods between 3-4 hours
P. Rodriguez-Gil, B. T. Gaensicke, H. -J. Hagen +15
[Abridged] We present time-series optical photometry of five new CVs identified by the Hamburg Quasar Survey. The eclipses observed in HS 0129+2933, HS 0220+0603, and HS 0455+8315…
A detection of the donor star of Aquila X-1 during its 2004 outburst?
R. Cornelisse, J. Casares, D. Steeghs +4
Phase-resolved high resolution optical spectroscopy has revealed narrow N III and He II emission lines from the soft X-ray transient Aquila X-1 during its 2004 outburst that move a…
SS433:the microquasar link with ULXs?
P. A. Charles, A. D. Barnes, J. Casares +6
SS433 is the prototype microquasar in the Galaxy and may even be analogous to the ULX sources if the jets' kinetic energy is taken into account. However, in spite of 20 years of st…
