We present estimates for the occurrence rates of hot Jupiters around dwarf stars based on data from Transiting Exoplanet Survey Satellite (TESS) Prime Mission. take 97 orbiting 198,721 AFG (ranging in mass $0.8M_{\odot}$ to $2.3M_{\odot}$) an independent search using TESS Mission data. estimate our planet sample's false positive as $14\pm7\%$ A stars, $16\pm6\%$ F and $0\%$ G stars. find Jupiter $0.29 \pm 0.05\%$ $0.36 0.06\%$ $0.55 0.14\%$ with a weighted average across $0.33\pm0.04\%$. Our results show correlation between higher abundance lower stellar mass, are good agreement found by Kepler. After correcting presence binaries sample, we single-star rate $0.98\pm0.36\%$ This is radial velocity (RV) surveys, indicating that multiplicity correction able resolve discrepancy transits RVs.
