CoRoT-4 (formerly known as CoRoT-Exo-4 [6] ) is a yellow-white dwarf main-sequence star in the constellation Monoceros. [3]
The star is orbited by one known extrasolar planet, designated CoRoT-4b. It was catalogued as part of the CoRoT mission to find transiting planets, when a planet was spotted using the transit method. [5]

CoRoT was a space telescope mission which operated from 2006 to 2013. The mission's two objectives were to search for extrasolar planets with short orbital periods, particularly those of large terrestrial size, and to perform asteroseismology by measuring solar-like oscillations in stars. The mission was led by the French Space Agency (CNES) in conjunction with the European Space Agency (ESA) and other international partners.
A super-Jupiter is a gas giant exoplanet that is more massive than the planet Jupiter. For example, companions at the planet–brown dwarf borderline have been called super-Jupiters, such as around the star Kappa Andromedae.
CoRoT-1b is a transiting extrasolar planet approximately 2,630 light-years away in the constellation of Monoceros. The planet was discovered orbiting the yellow dwarf star CoRoT-1 in May 2007. The planet was the first discovery by the French-led CoRoT Mission.
OGLE-TR-211 is a magnitude 15 star located about 6,000 light years away in the constellation of Carina.
CoRoT-2b is the second extrasolar planet to be detected by the French-led CoRoT mission, and orbits the star CoRoT-2 at a distance of 700 light years from Earth towards the constellation Aquila. Its discovery was announced on 20 December 2007. After its discovery via the transit method, its mass was confirmed via the radial velocity method.
CoRoT-3b is a brown dwarf or massive extrasolar planet with a mass 21.66 times that of Jupiter. The object orbits an F-type star in the constellation of Aquila. The orbit is circular and takes 4.2568 days to complete. It was discovered by the French-led CoRoT mission which detected the dimming of the parent star's light as CoRoT-3b passes in front of it.
CoRoT-4b is an extrasolar planet orbiting the star CoRoT-4. It is probably in synchronous orbit with stellar rotation. It was discovered by the French CoRoT mission in 2008.
CoRoT-5b is an extrasolar planet orbiting the F type star CoRoT-5. It was first reported by the CoRoT mission team in 2008 using a transit method. This planet has been confirmed by a Doppler follow-up study.
HAT-P-4 is a wide binary star consisting of a pair of G-type main-sequence stars in the constellation of Boötes. It is also designated BD+36°2593.
HAT-P-11, also designated GSC 03561-02092 and Kepler-3, is an orange dwarf metal rich star about 123 light-years away in the constellation Cygnus. This star is notable for its relatively large rate of proper motion. The magnitude of this star is about 9, which means it is not visible to the naked eye but can be seen with a medium-sized amateur telescope on a clear dark night. The age of this star is about 6.5 billion years.
CoRoT-1 is a yellow dwarf main sequence star similar to the Sun. The star is located approximately 2,630 light-years away in the constellation of Monoceros. The apparent magnitude of this star is 13.6, which means it is not visible to the naked eye; however, it can be seen through a medium-sized amateur telescope on a clear, dark night. The first exoplanet discovered in the course of the CoRoT mission orbits this star; it is considered to be a "hot Jupiter", and is approximately as massive as the planet Jupiter itself.
HAT-P-3, is a metal-rich K5 dwarf star located about 441 light-years away in the constellation Ursa Major. At a magnitude of about 11.5 it is not visible to the naked eye but is visible in a small to medium-sized amateur telescope. It is believed to be a relatively young star and has a slightly enhanced level of chromospheric activity.
CoRoT-2 is a yellow dwarf main sequence star a little cooler than the Sun. This star is located approximately 700 light-years away in the constellation of Aquila. The apparent magnitude of this star is 12, which means it is not visible to the naked eye but can be seen with a medium-sized amateur telescope on a clear dark night.
CoRoT-3 is a white-yellow dwarf main sequence star hotter than the Sun. This star is located approximately 2560 light-years away in the constellation of Aquila. The apparent magnitude of this star is 13, which means it is not visible to the naked eye but can be seen with a medium-sized amateur telescope on a clear dark night.
CoRoT-7 is a binary star system.
CoRoT-6 is a magnitude 13.9 star located in the Ophiuchus constellation.
CoRoT-5 is a magnitude 14 star located in the Monoceros constellation.
HAT-P-14b, officially named Sissi also known as WASP-27b, is an extrasolar planet located approximately 224.2 ± 0.6 parsecs (731.2 ± 2.0 ly) away in the constellation of Hercules, orbiting the 10th magnitude F-type main-sequence star HAT-P-14. This planet was discovered in 2010 by the HATNet Project using the transit method. It was independently detected by the SuperWASP project.
CoRoT-19b is a transiting exoplanet found by the CoRoT space telescope in 2011.
CoRoT-16 is a solitary star located in the equatorial constellation Scutum. With an apparent magnitude of 16, it requires a powerful telescope to be seen, and is located 2,400 light years away based on parallax.
