WASP-96 is a G8-type star, located approximately 1140 light-years from Earth in the constellation of Phoenix.

Contents

It is known to host at least one exoplanet, WASP-96b. It was discovered in 2013 by the Wide Angle Search for Planets (WASP), utilising the transit method. [2] In July 2022, NASA announced that a spectrum of the planet would be featured in the initial science release from the James Webb Space Telescope. [5] [6]

Planetary system

Observations from the James Webb Space Telescope show that WASP-96b displays a distinct signature of water, along with evidence for clouds and haze in its spectrum, [7] in contrast to what was previously believed to be an entirely cloudless atmosphere. [8] [9]

HD 189733 b is an exoplanet in the constellation of Vulpecula approximately 64.5 light-years away from our Solar System. Astronomers in France discovered the planet orbiting the star HD 189733 on October 5, 2005, by observing its transit across the star's face. With a mass 11.2% higher than that of Jupiter and a radius 11.4% greater, HD 189733 b orbits its host star once every 2.2 days at an orbital speed of 152.0 kilometers per second, making it a hot Jupiter with poor prospects for extraterrestrial life.

WASP-6, also officially named Márohu, is a type-G yellow dwarf star located about 651 light-years away in the Aquarius constellation. Dim at magnitude 12, it is visible through a moderate sized amateur telescope. The star is about 80% of the size and mass of the Sun and it is a little cooler. Starspots in the WASP-6 system helped to refine the measurements of the mass and the radius of the planet WASP-6b.

HD 15082 is a star located roughly 399 light years away in the northern constellation of Andromeda. The star is a Delta Scuti variable and a planetary transit variable.

In addition WASP-39b was the first exoplanet found to contain carbon dioxide in its atmosphere, and likewise for sulfur dioxide.

WASP-49 is a yellow dwarf main-sequence star. Its surface temperature is 5600 K. WASP-49 is depleted of heavy elements relative to Sun, with metallicity Fe/H index of -0.23, meaning it has an abundance of iron 59% of the Sun's level.

The data regarding starspot activity of WASP-69 are inconclusive, but spot coverage of the photosphere may be very high.

WASP-88 is a F-type main-sequence star. Its surface temperature is 6450±61 K. WASP-88 is similar to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of 0.03±0.04, and is younger at an age of 3.0±1.3 billion years.

WASP-80 is a K-type main-sequence star about 162 light-years away. The star's age is much younger than the Sun's at 1.352±0.222 billion years. WASP-80 is similar to the Sun in concentration of heavy elements, although this measurement is highly uncertain.
