2024年10月24日 · WASP-20 b is a gas giant exoplanet that orbits a G-type star. Its mass is 0.311 Jupiters, it takes 4.9 days to complete one orbit of its star, and is 0.06 AU from its star. Its discovery was announced in 2015.

WASP-20b is a transiting hot Jupiter discovered in 2014. [7] WASP-20b orbits WASP-20 in less than five Earth days very close to its star (0.06 AU) in a circular (near-zero eccentricity) orbit. The orbit is inclined by 85.56 ± 0.22° relative to the plane of the sky and is thus edge-on, as necessary for a transit to be observed. [5]

2014年2月6日 · We report the discovery of the planets WASP-20b and WASP-28b along with measurements of their sky-projected orbital obliquities. WASP-20b is an inflated, Saturn-mass planet (0.31 ; 1.46 ) in a 4.9-day, near-aligned () orbit around CD-24 102 (=10.7; F9).

WASP-20b is an inflated, Saturn-mass planet (0.31 MJup; 1.46 RJup) in a 4.9-day, near-aligned (λ = 12.7 ± 4.2°) orbit around CD-24 102 (V = 10.7; F9). Due to the low density of the planet and the apparent brightness of the host star, WASP-20 is a good target for atmospheric characterisation via transmission spectroscopy.

We announce the discovery that WASP-20 is a binary stellar system, consisting of two components separated by 0.2578 ± 0 0007 on the sky, with a flux ratio of 0.4639 ± 0.0015 in the K-band.

2022年11月15日 · We analyzed transmission spectra of the hot Saturn WASP-20b in the K band (1981–2394 nm) that were acquired with CRIRES+ with the aim to detect the signature of H 2 O and CO.

WASP-20b is an inflated, Saturn-mass planet (0.31 M Jup; 1.46 R Jup) in a 4.9-day, near-aligned (λ = 12.7 ± 4.2°) orbit around CD-24 102 (V = 10.7; F9). Due to the low density of the planet and the apparent brightness of the host star, WASP-20 is a good target for atmospheric characterisation via transmission spectroscopy.
