OGLE-TR-132 is a distantmagnitude 15.72star in the star fields of theconstellationCarina. Because of its great distance, about 4,900light-years, and location in the crowded field it was not notable in any way. Because its apparent brightness changes when one of its planets transits, the star has been given thevariable star designation V742 Carinae. Thespectral type of the star istype F. A yellow-white, verymetal-richdwarf star, it is slightly hotter and moreluminous than theSun.
In 2003 theOptical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star'slight curve indicating atransiting,planetary-sized object.[1] Since low-massred dwarfs andbrown dwarfs may mimic a planetradial velocity measurements were necessary to calculate the mass of the body. In 2004 the object was proved to be a new transitingextrasolar planet,OGLE-TR-132b.[3]
