Abstract
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 = 1 R J, in an orbit of P orb = 1.5 days around a low mass, M ⋆ = 0.7 M ⊙, mid-K main-sequence star. Finally, Qatar-10b is a hot, T eq ∼ 2000 K, sub-Jupiter mass planet, M P = 0.7 M J, with a radius of R P = 1.54 R J and an orbital period of P orb = 1.6 days, placing it on the edge of the sub-Jupiter desert.
