## TL;DR

This paper reports the discovery of three new exoplanets from the Qatar Exoplanet Survey, including a hot Saturn and two hot Jupiters, with detailed characterization of their masses, radii, and orbital periods.

## Contribution

The paper introduces three newly discovered exoplanets with detailed physical and orbital parameters, expanding the known diversity of hot exoplanets from the Qatar Exoplanet Survey.

## Key findings

- Qatar-8b is a hot Saturn with 0.37 Mjup and 1.3 Rjup, orbiting every 3.7 days.
- Qatar-9b is a hot Jupiter with 1.2 Mjup and 1 Rjup, orbiting every 1.5 days.
- Qatar-10b is a hot sub-Jupiter with 0.7 Mjup, 1.54 Rjup, and a 1.6-day orbit.

## Abstract

In this paper we present three new extrasolar planets from the Qatar Exoplanet Survey (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 Jupiter with 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-sequence star. Finally, Qatar-10b is a hot, Teq ~ 2000 K, sub-Jupiter mass planet, Mpl = 0.7 Mjup, with a radius of Rpl = 1.54 Rjup and an orbital period of Porb = 1.6 days, placing it on the edge of the sub-Jupiter desert.
