In 31 CVs, the white dwarf (WD) is recognisable through its broad Lyα absorption profile and we measure the WD effective temperatures (Teff) by fitting the HST data of these 31 systems assuming log g = 8.35, which corresponds to the average mass for CV WDs (0.8M⊙). Our results nearly double the number of CV WDs with an accurate temperature measurement.STAMPAenConference paper2-s2.0-85041115530https://pos.sissa.it/255/032/2015gacv.workE..32PFIS/05 - ASTRONOMIA E ASTROFISICAScienze Fisiche Settori ERC (ERC) di riferimento::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
