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]

WASP-1 is a metal-rich magnitude 12 star located about 1,300 light-years away in the Andromeda constellation.

WASP-2 is a binary star system in the Delphinus constellation located about 500 light-years away. The primary is magnitude 12 orange dwarf star, orbited by red dwarf star on wide orbit. The star system shows an infrared excess noise of unknown origin.

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 yellow dwarf star located about 910 light-years away in the Phoenix constellation. The star is likely older than Sun, slightly enriched in heavy elements and is rotating rapidly, being spun up by the tides raised by the giant planet on the 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 1,300 light-years away in the constellation Scorpius.

WASP-18 is a magnitude 9 star located in the Phoenix constellation of the southern hemisphere. It has a mass of 1.25 solar masses.

WASP-19 is a magnitude 12.3 star 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.

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. 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 400 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-121, also known as CD-38 3220, is a magnitude 10.4 star located approximately 850 light-years away in the constellation Puppis. WASP-121 has a mass and radius similar to the Sun's.

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.

WASP-26 is a yellow main sequence star in the constellation of Cetus.

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.

WASP-45 is a K-type main-sequence star about 690 light-years away. The star age cannot be well constrained, but it is probably older than Sun. Yet, WASP-45 is enriched in heavy elements compared to Sun, having 240% of solar abundance.

Qatar-2 is a K-type main-sequence star about 595 light-years away. The star is much older than Sun, and has a concentration of heavy elements similar to solar abundance. The star features a numerous and long-lived starspots, and belongs to a peculiar variety of inflated K-dwarfs with strong magnetic activity inhibiting internal convection.

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.
