目标。对CoRoT褐矮星的研究进行了总结。方法.利用CoRoT测光时间序列和地面径向速度测量研究了类太阳恒星周围的凌日褐矮星。结果CoRoT在F和G矮星周围发现了三颗凌日棕矮星。发现类太阳恒星周围褐矮星的出现率为0.20 +/- 0.15%，这与Kepler数据获得的值一致。
Aims. A summary of the CoRoT brown dwarf investigations are presented. Methods. Transiting brown dwarfs around solar like stars were studied by using the photometric time-series of CoRoT, and ground based radial velocity measurements. Results. CoRoT detected three transiting brown dwarfs around F and G dwarf stars. The occurence rate of brown dwarfs was found to be 0.20 +/- 0.15% around solar-like stars which is compatible with the value obtained by Kepler-data.
