    Doppler tomography of the black hole binary A0620-00 and the origin of chromospheric emission in quiescent X-ray binaries
    Context. Doppler tomography of emission line profiles in low-mass X-ray binaries allows us to disentangle the different emission sites and study the structure...
  • Publication
    Doppler tomography of XTE J1118+480 revealing chromospheric emission from the secondary star
    Doppler tomography of emission lines in low-mass X-ray binaries allows us to investigate the structure and variability of the accretion discs as well as...
