The hard X-rays from accreting white dwarfs openParWDsclosePar in magnetic cataclysmic variables openParCVsclosePar are produced by shock-heating in the accretion column comma and the measured temperature depends on the mass of the WD. By obtaining high-quality hard X-ray spectra comma it is possible to measure the temperature and constrain the WD mass. An important question is whether the WD mass distribution extends up to the Chandrasekhar limit. The best place to look for high-mass WDs is among CVs with the hardest spectra comma making CVs found in the 20-100 keV INTEGRAL survey good candidates for having more massive WDs. We propose NuSTAR and XMM observations of two IGR CVs.
