2024年10月24日 · WASP-189 b is a gas giant exoplanet that orbits a A-type star. Its mass is 1.99 Jupiters, it takes 2.7 days to complete one orbit of its star, and is 0.05053 AU from its star. Its discovery was announced in 2020.

WASP-189 b (also known as HD 133112 b) is an extrasolar planet that has an orbital period around its host star, WASP -189 (HD 133112), of less than three earth days, and is about 322 light-years away in the Libra constellation. [1][2][4] It was first discovered in 2018, and was observed in 2020 by CHEOPS.

2020年9月28日 · ESA’s exoplanet mission Cheops has observed the WASP-189 system and determined key parameters about the star and its planet, WASP-189b. Cheops observed WASP-189b at is passed behind its host star – an occultation – and recorded the dip in light from the entire system as it briefly slipped out of view.

This page summarises the information held within TEPCat for the transiting planetary system WASP-189. Please see here for descriptions of the quantities given below.

2018年9月13日 · We report the discovery of WASP-189b: an ultra-hot Jupiter in a 2.72-d transiting orbit around the V = 6.6 A star WASP-189 (HR 5599). We detected periodic dimmings in the star's lightcurve, first with the WASP-South survey …

At a visual magnitude of V = 6.6, WASP-189 is the brightest host star of all the WASP planets. The discovery of the transiting hot Jupiter was announced in 2018 in a paper led by David Anderson.

2022年1月12日 · We analyse the photometric observations of WASP-189 acquired with the instrument CHEOPS to derive constraints on the system architecture and the planetary atmosphere. We implement a light curve model suited for asymmetric transit shape caused by the gravity-darkened photosphere of the fast-rotating host star.

The planet WASP-189 b is a gas giant, more than 1.5 times the size of Jupiter. It is about 20 times closer to its host star than the Earth to the Sun. WASP-189 b is one of the hottest exoplanets known: CHEOPS scientists have measured its temperature …
