  - "AM CVn stars are ultra-compact semi-detached binaries consisting of a white dwarf
    primary and a hydrogen-depleted secondary. In this\r\npaper, we present spectroscopic
    and photometric results of 15 transient sources pre-classified as AM CVn candidates.
    Our analysis confirms\r\n9 systems of the type AM CVn, 3 hydrogen-rich cataclysmic
    variables (accreting white dwarfs with near-main-sequence stars for donors),\r\nand
    3 systems that could be evolved cataclysmic variables. Eight of the AM CVn stars
    are analysed spectroscopically for the first time,\r\nwhich increases the number
    of spectroscopically confirmed AM CVns by about 10%. TESS data revealed the orbital
    period of the AM CVn\r\nstar ASASSN-20pv to be Porb =27.282 min, which helps to
    constrain the possible values of its mass ratio. TESS also helped to determine\r\nthe
    superhump periods of one AM CVn star (ASASSN-19ct, Psh =30.94 min) and two cataclysmic
    variables we classify as WZ Sge stars\r\n(Psh =90.77 min for ZTF18aaaasnn and
    Psh =91.6min for ASASSN-15na).We identified very different abundances in the spectra
    of theAM\r\nCVns binaries ASASSN-15kf and ASASSN-20pv (both Porb ∼27.5min), suggesting
    different type of donors. Six of the studied AMCVns are\r\nX-ray sources, which
    helped to determine their mass accretion rates. Photometry shows that the duration
    of all the superoutbursts detected\r\nin the AM CVns is consistent with expectations
    from the disc instability model. Finally, we provide refined criteria for the
    identification of\r\nnew systems using all-sky surveys such as LSST.@eng"
