Planetary transit variables

HAT-P-27, also known as WASP-40, is the primary of a binary star system about 659 light-years away. It is a G-type main-sequence star. The star's age is similar to the Sun's at 4.4 billion years. HAT-P-27 is enriched in heavy elements, having a 195% concentration of iron compared to the Sun.

WASP-78, is a single F-type main-sequence star about 2350 light-years away. It is likely to be younger than the Sun at 3.4 billion years. WASP-78 is depleted in heavy elements, having a 45% concentration of iron compared to the Sun.

HAT-P-26 is a K-type main-sequence star located about away in the constellation of Virgo. A survey in 2015 did not find any stellar companions in orbit around it, although a red dwarf companion with a temperature is suspected on wide orbit.

K2-58 (also designated as EPIC 206026904) is a G-type main-sequence star in the constellation of Aquarius, approximately 596 light-years from the Solar System. The star is metal-rich, having 155% of the Solar abundance of elements heavier than helium. The star is located in a region where a hypothetical observer in the K2-58 system can see Venus transiting the Sun.

WASP-56 is a sun-like star of spectral type G6 about 1,070 light-years away in the constellation of Coma Berenices. It has an apparent magnitude of 11.48. Observations at the Calar Alto Observatory using the lucky imaging technique detected a candidate companion star located 3.4 arcseconds away, however it was not known if this is an actual binary companion or an optical double. It was confirmed in 2019 using Gaia DR2 data.

WASP-66, also known as TYC 7193-1804-1, is an F-type star in the constellation Antlia. It has an apparent magnitude of 11.6, which is much too faint to be seen with the unaided eye and is located at a distance of .

WASP-76, also known as BD+01 316, is a yellow-white main sequence star in the constellation of Pisces. A suspected stellar companion at a projected separation of 85 astronomical units was reported in 2014.

WASP-50, also named Chaophraya, is a G-type main-sequence star about 594 light-years away in the constellation Eridanus. The star is older than the Sun and slightly depleted in heavy elements compared to the Sun, and has a close to average starspot activity. Despite its advanced age, the star is rotating rapidly, being spun up by the tides raised by a giant planet on a close orbit.

WASP-42 is a K-type main-sequence star about 580 light-years away in the constellation Centaurus. Its surface temperature is 5315 K. WASP-42 is similar to the Sun in concentration of heavy elements, with metallicity ([Fe/H]) of 0.05, and is much older than the Sun at billion years. The star does exhibit starspot activity as is typical for its spectral class.

WASP-72 (also known as CD-30 1019 and officially named Diya) is the primary of a binary star system. It is an F7 class dwarf star, with an internal structure just on the verge of the Kraft break. It is orbited by a planet, WASP-72b. The age of WASP-72 is younger than the Sun at 3.55 billion years.

WASP-84, also known as BD+02 2056, is a G-type main-sequence star away in the constellation Hydra. Its surface temperature is 5350 K and is slightly enriched in heavy elements compared to the Sun, with a metallicity Fe/H index of 0.05. It is rich in carbon and depleted of oxygen. WASP-84's age is probably older than the Sun at 8.5 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.

Qatar-2 is a K-type main-sequence star about 595 light-years away in the constellation of Virgo. 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-25 is a G-type main-sequence star about 701 light-years away in the constellation of Hydra.

WASP-64, also named Atakoraka, is a star about 1,177 light-years away in the constellation Canis Major. It is a G7 class main-sequence star, orbited by a planet WASP-64b. It is younger than the Sun at 3.6 billion years, and it has a metal abundance similar to the Sun. The star is rotating rapidly, being spun up by the giant planet in a close orbit.
