Analysis of spiral structure in the accretion disc of the novalike Cataclysmic Variable EC21178--5417

We present an extensive Doppler tomography study of the eclipsing novalike EC21178--5417, which exhibits the classic accretion disc signature in the form of double-peak emission lines in its spectrum. Doppler tomograms confirm the presence of a strong, two-armed spiral pattern visible in the majorit...
