AllWISE & NEOWISE LCs of Red MSX massive YSOs

Out of the 806 sources, we obtain reliable 9yr long MIR magnitude variability data of 331 sources at the 3.4{mu}m (W1) and 4.6{mu}m (W2) bands by cross-matching the MYSO positions with ALLWISE and NEOWISE catalogs. After applying the variability selections using ALLWISE data, we identify five MIR-variable candidates.

The light curves show various classes, with the periodic, plateau-like, and dipper features. Out of the obtained two color-magnitude diagram of W1 and W1-W2, one shows "bluer when brighter and redder when fainter" trends in variability, suggesting change in extinction or accretion rate. Finally, our results show that G335.9960-00.8532 has a periodic light curve, with an ~690d cycle.
