COROT-4 (formerly known as COROT-Exo-4[6]) is a yellow-white dwarf main-sequence star in the constellation Monoceros.[1]
Planetary system
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]
