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