PublicationBowen Fluorescence from the Companion Star in X1822-371
We present clear evidence for the motion of the companion star in the low-mass X-ray binary (LMXB) X1822-371. We detect N III λ4640 emission moving in antiphase...

PublicationBroad iron emission line and kilohertz quasi-periodic oscillations in the neutron star system 4U 1636-53
Both the broad iron (Fe) line and the frequency of the kilohertz quasi-periodic oscillations (kHz QPOs) in neutron star low-mass X-ray binaries (LMXBs) can...

PublicationBurst-properties as a function of mass accretion rate in GX 3+1
GX 3+1 is a low-mass X-ray binary that is persistently bright since its discovery in 1964. It was found to be an X-ray burster twenty years ago proving that the...

PublicationBursts, eclipses, dips and a refined position for the luminous low-mass X-ray binary in the globular cluster Terzan 6
GRS 1747-312 is a bright transient X-ray source in the globular cluster Terzan 6 with quasi-periodic outbursts approximately every 4.5 months. We carried out 2...
