Qatar Exoplanet Survey: Qatar-8b, 9b, and 10b - A Hot Saturn and Two Hot Jupiters

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-circle dot, mid-K main-sequence star. Finally, Qatar-10b is a hot, T-eq similar to 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.
