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

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 ? ?=?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.
