OGLE-TR-132 is a distant magnitude 15.72 star in the star fields of the constellation Carina. Because of its great distance, about 4,900 light-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 the variable star designation V742 Carinae. The spectral type of the star is type F. A yellow-white, very metal-rich dwarf star, it is slightly hotter and more luminous than the Sun.

Planetary system
In 2003 the Optical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star's light curve indicating a transiting, planetary-sized object.[1] Since low-mass red dwarfs and brown dwarfs may mimic a planet radial velocity measurements were necessary to calculate the mass of the body. In 2004 the object was proved to be a new transiting extrasolar planet, OGLE-TR-132b.[3]

OGLE-TR-132 es una estrella distante del Sol unos 4900 Años luz, que se encuentra en la constelación de Carina. Tiene una débil magnitud aparente de 15,72. La estrella ha sido clasificada como una estrella blanco-amarilla de la secuencia principal, del tipo espectral F, con una alta metalicidad, siendo un poco más caliente y luminosa que el Sol. Dado que la estrella es tan débil, lejana, y está localizada en las regiones superpobladas del espacio, no presentaba ninguna característica especial, y no había sido catalogada anteriormente.Другой контент может иметь иную лицензию.
