摘要：In this paper we present three new extrasolar planets from the Qatar Exoplanet Survey. Qatar-8b is a hot Saturn, with M P =0.37 M J and R P =1.3 R J , orbiting a solar-like star every P orb =3.7 days. Qatar-9b is a hot Jupiter with a mass of M P =1.2 M J and a radius of R P =1R J , in an orbit of P orb =1.5days around a low mass, M å =0.7 M e , mid-K main-sequence star. Finally, Qatar-10b is a hot, T eq ∼2000K, sub-Jupiter mass planet, M P =0.7 M J , with a radius of R P =1.54R J and an orbital period of P orb =1.6 days, placing it on the edge of the sub-Jupiter desert.
