2024年10月24日 · WASP-38 b is a gas giant exoplanet that orbits a F-type star. Its mass is 3.44 Jupiters, it takes 6.9 days to complete one orbit of its star, and is 0.07522 AU from its star. Its discovery was announced in 2010.

The star is known to host one exoplanet, designated WASP-38b or formally named 'Iztok'. The stellar classification of HD 146389 is F8, [3] which is an F-type star of uncertain luminosity class.

2010年10月5日 · We report the discovery of WASP-38b, a long period transiting planet in an eccentric 6.871815 day orbit. The transit epoch is 2455335.92050 +/- 0.00074 (HJD) and the transit duration is 4.663 hours. WASP-38b's discovery was enabled due to an upgrade to the SuperWASP-North cameras.

In this paper, we report the discovery of WASP-38b, an ec-centric giant planet in a 6.87 day orbit. The candidate was iden-tified in February 2010 in SuperWASP-North data. Radial veloc-ity followup started at the end of March with FIES (2.6m NOT).

2010年12月1日 · We report the discovery of WASP-38b, a long period transiting planet in an eccentric 6.871815 day orbit. The transit epoch is 2 455 335.92050 ± 0.00074 (HJD) and the transit duration is 4.663 h. Methods. WASP-38b’s discovery was enabled due to an upgrade to the SuperWASP-North cameras.

The planet WASP-38b is 1.08 times the radius of Jupiter, the largest planet in our Solar System. It is thus about ten times the radius of our Earth. WASP-38b is roughly 2 and a half the mass of Jupiter so is about twice as dense as Jupiter. Maybe it has a dense rocky core surrounded by an envelope of hydrogen gas.

Aims: We report the discovery of WASP-38b, a long period transiting planet in an eccentric 6.871815 day orbit. The transit epoch is 2 455 335.92050 ± 0.00074 (HJD) and the transit duration is 4.663 h. Methods: WASP-38b's discovery was enabled due to an upgrade to the SuperWASP-North cameras.

We present observations of the Rossiter–McLaughlin effect for the transiting exoplanets WASP-1b, WASP-24b, WASP-38b and HAT-P-8b, and deduce the orientations of the planetary orbits with respect to the host stars’ rotation axes. The planets WASP-24b, WASP-38b and HAT-P-8b appear to move in prograde orbits and be well aligned, having sky-projected spin-orbit angles consistent with zero: λ ...

We report the discovery of WASP-38b, a long period transiting planet in an eccentric 6.871815 day orbit. The transit epoch is 2455335.92050 0.00074 (HJD) and the transit duration is 4.663 hours.

WASP-38b (Barros et al. 2011) is a Jovian planet that surprisingly moves in prograde orbits well aligned, despite the orbital eccentricity (Brown et al. 2012). ...
