cds-question@unistra.frmagellanic-cloudsinfrared-sourceslate-type-starsvariable-starsVariability is a key property of stars on the asymptotic giant branch (AGB). Selection criteria are derived based on colour-colour and colour-magnitude diagrams from the combination of VISTA Magellanic Cloud (VMC) survey, Spitzer IRAC, and AllWISE data. After eliminating LPVs with known periods shorter than 450 days, a sample of 1299 candidate obscured AGB stars is selected. K-band LCs are constructed combining the epoch photometry available in the VMC survey with literature data, analysed for variability and fitted with a single period sine curve to derive mean magnitudes, amplitudes and periods. A subset of 254 stars are either new variables, or known variables where the period we find is better determined than the literature value, or longer than 1000 days. The spectral energy distributions (SEDs) of these stars are fitted to a large number of templates. For this purpose the SEDs and Spitzer IRS spectra of some non-AGB stars (Be stars, Hii regions and young stellar objects [YSOs]) are also fitted to have templates of the most likely contaminants in the sample. A sample of 217 likely LPVs is found. Thirty-four stars have periods longer than 1000 days although some of them have alternative shorter periods.2020A&A...636A..48Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/636/A48CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/351 : VISTA Magellanic Survey (VMC) catalog (Cioni+, 2011)J/A+A/531/A157 : LMC planetary nebulae (VMC Survey II) (Miszalski+, 2011)J/MNRAS/424/1807 : VISTA Magellanic Cloud Survey.
