XRISM spectroscopy of AM Herculis reveals bulk velocity and temperature gradients in the radiative cooling accretion column, with derived shock temperature of 24 keV, velocity of 1116 km/s, and density of 5-6 x 10^15 cm^-3.
XRISM/Resolve high-resolution spectroscopy detects coherent orbital modulation in Fe XXV Kα line centroids from EX Hydrae, yielding K1 = 58.1 km/s and a white dwarf mass of 0.79 solar masses consistent with optical tracers.
Balmer decrements in CV spectra form a diagnostic diagram that separates period-bouncers from pre-bounce systems via fitted logistic regression.
2CXO J0507 is a polar-type magnetic cataclysmic variable featuring a white dwarf with B ≈ 30 MG and an orbital period of 2.34 hours, identified through multiwavelength archival and follow-up data.
New timing and spectral analysis of EP240309a yields conservative upper limits on the white-dwarf magnetospheric radius of a few times 10^10 cm and detects an rms-flux relation in some TESS sectors.
