Abstract
In this study, 19 exoplanets were studied. Their photometric observations were obtained from the ETD. After performing the data reduction steps, its parameters were obtained through Exofast online software. Then calculated orbital parameters of planets and as a result, the periods of all the planets in this study match comparable with the Extrasolar Planets Encyclopedia. Also, we present Tc and Tdepth obtained from the observations. The location of the host stars in this study was also plotted in the H-R diagram
