cds-question@unistra.frcataclysmic-variable-starseclipsing-binary-starswhite-dwarf-starsnovaestellar-massesstellar-radiivisible-astronomysloan-photometryWe present measurements of the component masses in 15 Cataclysmic Variables (CVs) - 6 new estimates and 9 improved estimates. We provide new calibrations of the relationship between superhump period excess and mass ratio, and use this relation to estimate donor star masses for 225 superhumping CVs. With an increased sample of donor masses we revisit the implications for CV evolution. We confirm the high mass of white dwarfs in CVs, but find no trend in white dwarf mass with orbital period. We argue for a revision in the location of the orbital period minimum of CVs to 79.6+/-0.2min, significantly shorter than previous estimates. We find that CV donors below the gap have an intrinsic scatter of only 0.005R_{sun}_ around a common evolutionary track, implying a correspondingly small variation in angular momentum loss (AML) rates. In contrast to prior studies, we find that standard CV evolutionary tracks - without additional AML - are a reasonable fit to the donor masses just below the period gap, but that they do not reproduce the observed period minimum, or fit the donor radii below 0.1M_{sun}_.2019MNRAS.486.5535Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/486/5535CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/486/5535https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/486/5535http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/486/5535https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/486/5535https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/486/5535http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/486/5535GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/486/5535/table1 (Ephemerides for the CVs modelled in this paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/486/5535/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/486/5535/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/486/5535/table1?GETtext/xml+votable180.050000true195.1210417-30.88252780.005555555555555556Cone search capability for table J/MNRAS/486/5535/table2 (System parameters for the 15 eclipsing systems analysed in this paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/486/5535/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/486/5535/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/486/5535/table2?GETtext/xml+votable180.050000true211.2250319-10.45056440.005555555555555556Cone search capability for table J/MNRAS/486/5535/table3 (Orbital (Porb) and superhump (Psh) periods of the systems used to calibrate the {epsilon}(q) relation)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/486/5535/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/486/5535/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/486/5535/table3?GETtext/xml+votable180.050000true226.843207852.51105690.005555555555555556Cone search capability for table J/MNRAS/486/5535/tablea1 (System parameters for supplementary systems)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/486/5535/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/486/5535/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/486/5535/tablea1?GETtext/xml+votable180.050000true218.324115610.18985690.005555555555555556Cone search capability for table J/MNRAS/486/5535/tablec1 (Journal of observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/486/5535/tablec1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/486/5535/tablec1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/486/5535/tablec1?GETtext/xml+votable180.050000true211.2250319-10.45056440.0055555555555555566/1346 3029 4279 4479 4515 4790 5062 5191 5457 5833 6075-6076 6668 7194 8359 9165 9333 11168 11319 11456 12859 14441 15036 15090 15110 15590 16046 17886 19009 20066 21822 22360 22771 22901 25683 25934 27419 29217 30315 33067 36221 36743 37022 37252 39459 39720 40255 43940 43947 46400 47540 47964https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/486/5535?format=asciiOpticaldefaultJ/MNRAS/486/5535/table1Ephemerides for the CVs modelled in this paperSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
