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 ExoplanetSurvey (QES). Qatar-8b is a hot Saturn, with Mpl = 0.37 Mjup and Rpl = 1.3 Rjup, orbiting a solar-like star every Porb = 3.7 days. Qatar-9b is a hot Jupiterwith a mass of Mpl = 1.2 Mjup and a radius of Rpl = 1 Rjup, in a Porb = 1.5 days orbit around a low mass, Mstar = 0.7 Msun, mid-K main-sequencestar. Finally, Qatar-10b is a hot, Teq ~ 2000 K, sub- Jupiter massplanet, Mpl = 0.7 Mjup, with a radius of Rpl = 1.54 Rjup and an orbital periodof Porb = 1.6 days, placing it on the edge of the sub- Jupiterdesert.
