cds-question@unistra.frvariable-starsinfrared-photometryvisible-astronomybroad-band-photometryV725 Sgr is a rather peculiar variable that showed a period increase during part of the twentieth century. Its behavior is attributed to rapid stellar evolution. V725 Sgr was monitored in V, R, I and J, H, K with the REM telescope, on La Silla, from 2008 August to 2009 November. Its light variation does not show a well-defined cyclic behavior. Its current V is similar to what it was 30-40yrs ago. Its published motion suggests that V725 Sgr is located at a few kiloparsecs from the Sun. This implies that V725 Sgr is a giant rather than a supergiant star. From its mean colors we conclude that V725 Sgr is now an irregular variable of spectral type ~K4 III.2010PASP..122..144Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/122/144CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/122/144https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/122/144http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/122/144https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/122/144https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/122/144http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/122/144GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/PASP/122/144/table2Photometry of V725 SgrrecnoRecord number assigned by the VizieR team.
