Abstract : HD 118660 is a delta scuti star possibly in the main sequence phase. The star shows a multi periodic pulsational behavior. The main target of our study is to investigate the asteroseismic analysis of HD 118660 using the space based TESS data. Our analysis conclude that the star is pulsating in radial and non radial modes with radial overtones between 1 to 6 for angular mode l=1and 1 to 5 for angular mode l=0. The star is also showing amplitude modulation of pulsation that is either due to the beating of close frequencies and or some unknown reasons. However we have not detected any frequency modulation. The location of the star in the H-R diagram shows that the star is close to the main sequence phase where H is burning in the core.
