2024年10月24日 · WASP-47 b is a gas giant exoplanet that orbits a G-type star. Its mass is 1.17674 Jupiters, it takes 4.2 days to complete one orbit of its star, and is 0.052 AU from its star. Its discovery was announced in 2012.

WASP-47 is a G-type main-sequence star of spectral type G9V, making it quite similar to the Sun. It is 1.11 M☉ and 1.16 R☉, with a temperature of 5576 K and an age of about 6.5 billion years. In comparison, the Sun has a slightly higher temperature of 5778 K but is significantly younger, at 4.5 billion years old. [7]

A Low Stellar Obliquity for WASP-47, a Compact Multiplanet System with a Hot Jupiter and an Ultra-short Period Planet Sanchis-Ojeda et al. 2015 | Reference Overview Hot Jupiters with relatives: discovery of additional planets in orbit around WASP-41 and WASP-47

CAMPAIGN: Planet included in one of the current observing campaings. TTVs: Planet exhibiting strong Trasit Time Variations due to another planet or orbital decay. ALERT: Observations in the last 2 years show an O-C greater than 10 minutes. HIGH: Prediction uncertainty greater than the target or less than 3 epochs observed in the last 2 years.

2015年10月20日 · Visual inspection of the Kepler data revealed that it was much more than that – two other planets were found transiting WASP-47, a super-Earth sized planet just inside the hot Jupiter’s orbit and a Neptune-sized planet just outside (figure 2). Figure 2.

Detailed information about planet WASP-47 b and its parameters.

2015年8月10日 · Using new data from the K2 mission, we show that WASP-47, a previously known hot Jupiter host, also hosts two additional transiting planets: a Neptune-sized outer planet and a super-Earth inner companion.

2007年1月12日 · This page summarises the information held within TEPCat for the transiting planetary system WASP-47b. Please see here for descriptions of the quantities given below.

The planetary system WASP-47 is highly popular at the moment, following the K2 discovery of two more transiting exoplanets, and the radial-velocity detection of a longer-period outer planet, in addition to the orginal hot Jupiter, WASP-47b.

2020年3月30日 · The WASP-47 system has been described as "the gift that keeps on giving," with numerous exoplanet discoveries beyond the initial discovery of the hot Jupiter, WASP-47b. The orbital architecture of the system that combines compact orbits with a giant planet in an eccentric orbit in the HZ presents an interesting dynamical configuration.
