To study properties of the variation of the infrared emission of OH/IR stars, we collect and analyze the infrared observational data in K band for nine OH/IR whole wheat phyllo dough stars.We use the observational data obtained for about three decades including recent data from the two micron all sky survey (2MASS) merlin wizard costume and the deep near infrared survey of the southern sky (DENIS).We use Marquardt-Levenberg algorithm to determine the pulsation period and amplitude for each star and compare them with previous results of infrared and radio investigations.
