OGLE-TR-113
OGLE-TR-113 is a dim, distant magnitude 16 binary star in the star fields of the constellation Carina. Because of its distance of about 1800 light years,〔 and location in a crowded field it was not notable in any way. Spectral type of the star is type K dwarf star, slightly cooler and less luminous than the Sun.〔(【引用サイトリンク】 title =SIMBAD query result: SBC9 2451 -- Spectroscopic binary )〕 ==Planetary system== However, in 2002 the Optical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star's light curve indicating a transiting, planetary-sized object.〔 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-113b.〔
