cds-question@unistra.frmagellanic-cloudsvariable-starsinfrared-photometryvisible-astronomyphotometryMira variables are asymptotic giant-branch pulsating stars with long pulsation periods and large amplitudes in optical bands. By applying the random forest algorithm to the I-band light curves for the Miras in the Magellanic Clouds, we have classified these Miras into regular Miras and nonregular Miras. Nonregular Miras exhibit a long-term variation in addition to their primary pulsation periods. Our results confirm that the period-luminosity relation for maximum light has a small dispersion, but only occurs on the regular oxygen-rich Miras, which we recommend to be applied in future distance-scale work. We have also collected multiband photometry for these Miras to perform a spectral energy distribution fitting with stellar and dust components, showing that a significant fraction of dust is present around the nonregular Miras. According to our results, we believe that the periodic long-term variations seen in the nonregular Miras might be due to the presence of dust.2022AJ....163..192Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/163/192CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/297 : NOMAD Catalog (Zacharias+ 2005)I/305 : The Guide Star Catalog, Version 2.3.2 (GSC2.3) (STScI, 2006)I/317 : The PPMXL Catalog (Roeser+ 2010)I/319 : XPM Catalog of positions and proper motions (Fedorov+ 2011)I/320 : SPM 4.0 Catalog (Girard+, 2011)I/322 : UCAC4 Catalogue (Zacharias+, 2012)II/328 : AllWISE Data Release (Cutri+ 2013)I/331 : Absolute Proper motions Outside the Plane (APOP) (Qi+, 2015)I/337 : Gaia DR1 (Gaia Collaboration, 2016)I/339 : Hot Stuff for One Year (HSOY) (Altmann+, 2017)I/340 : UCAC5 Catalogue (Zacharias+ 2017)I/345 : Gaia DR2 (Gaia Collaboration, 2018)II/358 : SkyMapper Southern Sky Survey.
