cds-question@unistra.frmagellanic-cloudsvariable-starsapparent-magnitude146 long-period red variable stars in the Large Magellanic Cloud (LMC) from the three-year Microlensing Observations in Astrophysics (MOA) project data base were analysed. A careful periodic analysis was performed on these stars and a catalogue of their magnitudes, colours, periods and amplitudes is presented. We convert our blue and red magnitudes to K-band values using 19 oxygen-rich stars. A group of red short-period stars separated from the Mira sequence has been found on a (log P,K) diagram. They are located at the short period side of the Mira sequence consistent with the work of Wood & Sebo (1996MNRAS.282..958W). There are two interpretations for such stars; a difference in pulsation mode or a difference in chemical composition. We investigated the properties of these stars together with their colour, amplitude and periodicity. We conclude that they have small amplitudes and less regular variability. They are likely to be higher-mode pulsators. A large scatter has also been found on the long-period side of the (logP,K) diagram. This is possibly a systematic spread given that the blue band of our photometric system covers both standard B and V bands and affects carbon-rich stars.2002MNRAS.330..137Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/330/137CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/99/784 : IR photometry of LMC long-period variables (Hughes+ 1990)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/330/137https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/330/137http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/330/137https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/330/137https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/330/137http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/330/137GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/330/137/table1 (146 selected long-period red variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/330/137/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/330/137/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/330/137/table1?GETtext/xml+votable180.050000true77.1459583-69.24945280.0055555555555555565/8274 6/33055 33090-33091 33094 33120https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/330/137?format=asciiOpticaldefaultJ/MNRAS/330/137/table1146 selected long-period red variablesrecnoRecord number assigned by the VizieR team.
