cds-question@unistra.frnovaephotometryRecurrent novae (RNe) are cataclysmic variables with two or more nova eruptions within a century. Classical novae (CNe) are similar systems with only one such eruption. Many of the so-called CNe are actually RNe for which only one eruption has been discovered. Since RNe are candidate Type Ia supernova progenitors, it is important to know whether there are enough in our Galaxy to provide the supernova rate, and therefore to know how many RNe are masquerading as CNe. To quantify this, we collected all available information on the light curves and spectra of a Galactic, time-limited sample of 237 CNe and the 10 known RNe, as well as exhaustive discovery efficiency records. We recognize RNe as having (1) outburst amplitude smaller than 14.5-4.5xlog(t_3_), (2) orbital period >0.6 days, (3) infrared colors of J-H>0.7 mag and H-K>0.1 mag, (4) FWHM of H{alpha}>2000 km/s, (5) high excitation lines, such as Fe X or He II near peak, (6) eruption light curves with a plateau, and (7) white dwarf mass greater than 1.2 M_{sun}_. Using these criteria, we identify V1721 Aql, DE Cir, CP Cru, KT Eri, V838 Her, V2672 Oph, V4160 Sgr, V4643 Sgr, V4739 Sgr, and V477 Sct as strong RN candidates. We evaluate the RN fraction among the known CNe using three methods to get 24%+/-4%, 12%+/-3%, and 35%+/-3%. With roughly a quarter of the 394 known Galactic novae actually being RNe, there should be approximately a hundred such systems masquerading as CNe.2014ApJ...788..164Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/788/164CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/173 : A REFERENCE CATALOGUE OF GALACTIC NOVAE (Version 1990.0)J/PAZh/34/270 : Photometric parameters of Galactic novae (Burlak+, 2008)J/PAZh/34/278 : Distances and extinction of Galactic novae (Burlak, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/788/164https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/788/164http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/788/164https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/788/164https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/788/164http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/788/164GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/788/164/table3 (Properties of the Known Galactic Classical Novae)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/788/164/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/788/164/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/788/164/table3?GETtext/xml+votable180.050000true8.042166741.97005560.0055555555555555565/7217 6/1694 2713 2922 3096 3588 6319 8474 12114 12888 12962 13216 13285 13286 13800 13975 14024 14201 14226 14228 14248 14254 14293 14336 14393 14409 14433 14498 14630 14634 14651 14720 14847 15014 15036 15385 15386 15502 21705 22076 23617 24118 24405 24487 24506 28687 28702 28705 28707 28710 28713 28714 28715 28716 28718 28719 28720 28724 28725 28727 28729 28730 28732 28734 28735 28741 28746 28758 28762 28764 28769 28771 28772 28780 28782 28783 28786 28787 28790 28792 28793 28798 28799 28820 28823 28833 28850 28858 28865 28866 28867 28873 28875 28876 28879 28882 28885 28887 28893 28904 28910 28960 28973 29002 29059 29063 29069 29084 29105 29109 29155 29167 29176 29190 29191 29209 29214 29249 29251 29265 29268 29272 29276 29279 29280 29285 29308 29478 29479 29487 29503 29509 29832 29871 29900 30208 30209 30215 30227 30231 30236 30239 30240 30284 30294 30300 30303 30315 30324 30389 30474 30498 30500 30502 30505 30521 30543 30640 30643 30652 30683 30717 30788 30970 31866 31942 32006 32017 32048 32121 37204 37824 37888 37922 37933 37994 38045 38919 39397 39756 39775 39888 39890 40460 41006 41543 41565 41583 41647 41671 41696 41738 41746 41766 41852 41860 41913 42143 42169 42351 42387 42487 42494 42837 42842 43031 43051 43080 47805 47822 47851 47864 48026https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/788/164?format=asciiOpticaldefaultJ/ApJ/788/164/refsReferencesBibcodeReference bibcodemeta.bib.bibcodecharComComment on referencemeta.notecharRefReferencemeta.ref;pos.framecharrecnoRecord number assigned by the VizieR team.
