TL;DR
This paper reports the discovery and characterization of three new hot Jupiter exoplanets, Qatar-3b, Qatar-4b, and Qatar-5b, identified by the Qatar Exoplanet Survey, including their masses, radii, and host star properties.
Contribution
The paper presents the first discovery and detailed characterization of three hot Jupiter exoplanets from the Qatar Exoplanet Survey, including their masses, radii, and host star parameters.
Findings
All three planets are heavy hot Jupiters with masses over 4 Jupiter masses.
The planets have short orbital periods ranging from 1.8 to 2.9 days.
Host stars are low-mass main sequence stars with well-measured properties.
Abstract
We report the discovery of Qatar-3b, Qatar-4b, and Qatar-5b, three new transiting planets identified by the Qatar Exoplanet Survey (QES). The three planets belong to the hot Jupiter family, with orbital periods of =2.50792 days, =1.80539 days, and =2.87923 days. Follow-up spectroscopic observations reveal the masses of the planets to be =4.31 , =6.10 , and = 4.32 , while model fits to the transit light curves yield radii of = 1.096 , = 1.135 , and = 1.107 . The host stars are low-mass main sequence stars with masses and radii = 1.145 , = 0.896 , = 1.128 and = 1.272…
