Abstract

We report the discovery of Qatar-3b, Qatar-4b, and Qatar-5b, three new transiting planets identified by the Qatar Exoplanet Survey. The three planets belong to the hot Jupiter family, with orbital periods of PQ3b=2.50792 days, PQ4b=1.80539 days, and PQ5b=2.87923 days. Follow-up spectroscopic observations reveal the masses of the planets to be MQ3b=4.31±0.47 MJ, MQ4b=6.10±0.54 MJ, and MQ5b=4.32±0.18 MJ, while model fits to the transit light curves yield radii of RQ3b=1.096±0.14 RJ, RQ4b=1.135±0.11 RJ, and RQ5b= 1.107±0.064 RJ. The host stars are low-mass main sequence stars with masses and radii MQ3= 1.145±0.064 Ṁ, MQ4=0.896±0.048Ṁ, MQ5=1.128±0.056 Ṁ and RQ3=1.272±0.14 RṀ, RQ4=0.849±0.063 R , and RQ5=1.076±0.051 Ṙ for Qatar-3, 4, and 5 respectively. The V magnitudes of the three host stars are VQ3=12.88, VQ4=13.60, and VQ5=12.82. All three new planets can be classified as heavy hot Jupiters (M > 4 MJ).
