description Overview

HAT-P-13b

HAT-P-13b is a transiting hot Jupiter discovered by the HATNet survey and announced in 2009. It circles its Sun-like host star in a short-period orbit, while the same system contains a more distant and substantially more eccentric companion detected through radial-velocity measurements. The system has been studied because interactions between the planets can help constrain the orbital dynamics and...

KELT-9b

KELT-9b is a giant exoplanet orbiting the star HD 189733A. It’s notable as the hottest known planet, boasting a dayside temperature exceeding 4,000 Kelvin – hotter than many stars. This ultrahot Jupiter was discovered by the Kentucky Extrasolar Traniting Survey (KELT) in 2017 and is of interest to astronomers studying extreme planetary atmospheres and transiting exoplanets.
