Photometry and spectroscopy of HD 80606b

We present new observations of a transit of the 111.4-day-period exoplanet HD80606b. Due to this long orbital period and to the orientation of the eccentric orbit (e=0.9), the...本研究报道了轨道周期为111.4天的系外行星（exoplanet）HD80606b的一次凌星观测新结果。鉴于该行星轨道周期极长，且其偏心轨道（eccentric orbit）的取向特殊（偏心率e=0.9），
