The 126 identified RSGs are classified into five categories accordingly: 20 with poor photometry, 55 with no reliable period, 6 with semi-regular variation, 15 with a long secondary period (LSP) and distinguishable short period, and 30 with only an LSP. For the semi-regular variables and the LSP variables with distinguishable short period, the K_S_-band period-luminosity (P-L) relation is analyzed and compared with that of the Galaxy, the Large Magellanic Cloud, and M33. It is found that the RSGs in these galaxies obey a similar P-L relation except for those in the Galaxy. In addition, the P-L relations in the infrared bands, namely, the 2MASS JHK_S_, Spitzer/IRAC, and Spitzer/MIPS 24 {mu}m bands, are derived with high reliability. The best P-L relation occurs in the Spitzer/IRAC [3.6] and [4.5] bands. Based on the comparison with the theoretical calculation of the P-L relation, the mode of pulsation of RSGs in the SMC is suggested to be the first-overtone radial mode.2012ApJ...754...35Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/754/35CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/305 : SAGE LMC and SMC IRAC Source Catalog (IPAC 2009)II/236 : UBVR CCD survey of the Magellanic clouds (Massey+, 2002)II/264 : ASAS Variable Stars in Southern hemisphere (Pojmanski+, 2002-2005)II/247 : Variable Stars in the Large Magellanic Clouds (MACHO, 2001)J/ApJ/727/53 : Red supergiant stars in the LMC.
