We conclude based on spectroscopy combined with archive photographs and modern CCD photometry that both peculiar red novae were binaries prior to their outbursts, and contained blue hot components that exploded. The secondary of V838 Mon is a hot B3V star, and that of V4332 Sgr is a cool M7 star.2007AZh....84..147Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/84/147CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/434/1107 : UBV(RI)c photometry of stars around V838 Mon (Munari+, 2005)J/ApJ/598/L43 : Polarimetry of V838 Mon and stars around (Wisniewski+, 2003)J/PAZh/28/764 : UBVR photometry of Nova Mon 2002 (V838 Mon) (Goranskii+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/84/147https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/84/147http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/84/147https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/84/147https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/84/147http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/84/147GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AZh/84/147/v4332sgrV4332 Sgr light curvesrecnoRecord number assigned by the VizieR team.
