It is confirmed that V396 Mon is a shallow W-type contact binary system with a mass ratio q=2.554(+/-0.004) and a degree of contact factor f=18.9%(+/-1.2%). A period investigation based on all available data shows that the period of the system includes a long-term decrease (dP/dt=-8.57x10^-8^days/yr) and an oscillation (A3=0.0160day, T3=42.4yr). They are caused by angular momentum loss and light-time effect, respectively. The suspect third body is possibly a small M-type star (about 0.31 solar mass).2011AJ....141...44Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/44CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/141/44https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/141/44http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/141/44https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/141/44https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/141/44http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/141/44GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/141/44/photOriginal data of V396 Mon in the BVRI bandsrecnoRecord number assigned by the VizieR team.
