WASP-43 is a K-type star about 284 light-years (87 parsecs) away in the Sextans constellation. It is about half the size of the Sun, and has approximately half the mass. WASP-43 has one known planet in orbit, a Hot Jupiter called WASP-43b.

WASP-43b, formally named Astrolábos, [2] is a transiting planet in orbit around the young, active, and low-mass star WASP-43 in the constellation Sextans. The planet is a hot Jupiter with a mass twice that of Jupiter, but with a roughly equal radius.

2024年10月24日 · WASP-43 b is a gas giant exoplanet that orbits a K-type star. Its mass is 1.78 Jupiters, it takes 0.8 days to complete one orbit of its star, and is 0.0142 AU from its star. Its discovery was announced in 2011.

2024年4月30日 · WASP-43 b is a Jupiter-sized planet roughly 280 light-years away, in the constellation Sextans. The planet orbits its star at a distance of about 1.3 million miles, completing one circuit in about 19.5 hours. Because it is so close to its star, WASP-43 b is probably tidally locked: Its rotation rate and orbital period are the same, such that ...

The orbital obliquity of three close-in massive planets hosted by dwarf K-type stars: WASP-43, HAT-P-20 and Qatar-2.

Thirty eclipses of the ultra-short period planet WASP-43 b. Detailed information about planet WASP-43 b and its parameters.

2023年1月16日 · We observed a full-orbit phase curve of the hot Jupiter WASP-43b with MIRI/LRS as part of the Transiting Exoplanet Community Early Release Science Program. Here we report preliminary findings for the instrument performance from …

2025年1月7日 · In this context, we aim to re-determine the orbital parameters of WASP-43b-in particular, orbital period, eccentricity, and argument of the periastron-and its orbital evolution. We study the outcomes of the tidal interaction with the host star:whether tidal decay and periastron precession are occurring in the system.
