Planetary system

In 2009, a planet of the star was announced by the SuperWASP project. It appears to be another hot Jupiter type exoplanet. [4]

In 2024, a candidate mini-neptune was detected, also using the transit method. Further observations are needed to confirm its existence. The planet takes ten days to fully orbit WASP-16 and has an equilibrium temperature of 810  K (537 °C). [7]

WASP-1 is a metal-rich magnitude 12 star located about 1,250 light-years away in the Andromeda constellation.

WASP-10 is a star in the constellation Pegasus. The SuperWASP project has observed and classified this star as a variable star, perhaps due to the eclipsing planet.

WASP-5 is a magnitude 12 G-type main-sequence star located about 1,020 light-years away in the Phoenix constellation. The star is likely older than the Sun, slightly enriched in heavy elements and is rotating rapidly, being spun up by the tides raised by the giant planet on a close orbit.

WASP-3 is a magnitude 10 yellow-white dwarf star located about 800 light-years away in the Lyra constellation. It appears to be variable; it "passed from a less active to a more active state between 2007 and 2010".

WASP-17 is an F-type main sequence star approximately 1,310 light-years away in the constellation Scorpius.

<span class="mw-page-title-main">WASP-16b</span>

WASP-16b is an extrasolar planet that travels around its star, WASP-16, every 3.12 days. Likely a hot Jupiter. Its mass is near .855 of Jupiter, the radius is 1.008 of Jupiter. It was discovered in 2009 by a team led by T.A. Lister as part of the Wide Angle Search for Planets project.

WASP-18 is a magnitude 9 star located 400 light-years away in the Phoenix constellation of the southern hemisphere. It has a mass of 1.29 solar masses.

WASP-19, formally named Wattle, is a magnitude 12.3 star about 869 light-years away, located in the Vela constellation of the southern hemisphere. This star has been found to host a transiting hot Jupiter-type planet in tight orbit.

<span class="mw-page-title-main">HD 15082</span> Star in the constellation Andromeda

HD 15082 is a star located roughly 397 light years away in the northern constellation of Andromeda. The star is a Delta Scuti variable and a planetary transit variable. A hot Jupiter type extrasolar planet, named WASP-33b or HD 15082b, orbits this star with an orbital period of 1.22 days. It is the first Delta Scuti variable known to host a planet.

HAT-P-24 is an F8 dwarf star about 413 parsecs away. A planet was discovered with the transit method by the HATNet Project in 2010. HAT-P-24b, is a typical hot Jupiter orbiting in only 3 days.

WASP-31b is a low-density (puffy) "hot Jupiter" extrasolar planet orbiting the metal-poor dwarf star WASP-31. The exoplanet was discovered in 2010 by the WASP project. WASP-31b is in the constellation of Crater, and is about 1305 light-years from Earth.

<span class="mw-page-title-main">WASP-21</span> Star in the constellation Pegasus

WASP-21 is a G-type star that is reaching the end of its main sequence lifetime approximately 850 light years from Earth in the constellation of Pegasus. The star is relatively metal-poor, having 40% of heavy elements compared to the Sun. Kinematically, WASP-21 belongs to the thick disk of the Milky Way. It has an exoplanet named WASP-21b.

WASP-25 is a yellow main sequence star in the constellation of Hydra.

WASP-37 is a yellow main sequence star in the constellation of Virgo.

HAT-P-16 is a F-type main-sequence star about 725 light-years away. The star has a concentration of heavy elements slightly higher than solar abundance, and low starspot activity. The survey in 2015 have failed to find any stellar companions to it. The spectral analysis in 2014 have discovered the HAT-P-16 has a carbon to oxygen molar ratio of 0.58±0.08, close to Sun`s value of 0.55.

WASP-62, formally named Naledi, is a single star about 573 light-years away. It is an F class main-sequence star, orbited by a planet, WASP-62b. The age of WASP-62 is much younger than the Sun at 0.8±0.6 billion years, and it has a metal abundance similar to the Sun.

WASP-61 is a single F-type main-sequence star about 1560 light-years away. The star is likely younger than the Sun at approximately 3.8+1.8
−0.9
billion years. WASP-61 is depleted in heavy elements, having just 40% of the solar abundance of iron.

WASP-84, also known as BD+02 2056, is a G-type main-sequence star 327 light-years away in the constellation Hydra. Its surface temperature is 5350±31 K and is slightly enriched in heavy elements compared to the Sun, with a metallicity Fe/H index of 0.05±0.02. It is rich in carbon and depleted of oxygen. WASP-84's age is probably older than the Sun at 8.5+4.1
−5.5
billion years. The star appears to have an anomalously small radius, which can be explained by the unusually high helium fraction or by it being very young.
