Analysis shows transit times for hot Jupiter Qatar-1b, indicating no additional bodies in the exoplanetary system.
Here, we present the transit times and transit timing variation (TTV) analysis of the hot Jupiter Qatar-1b, based on our archival observations. A total of 19 transit events were observed using the 0.6-m Zeiss-600 telescope at Maidanak Observatory in Uzbekistan. Transit light-curve fitting was performed using the Transit Analysis Package (TAP) software. Our results did not indicate the presence of any additional bodies in the observed exoplanetary system.
