| 摘 要： | 为对太阳系外行星的物理参数进行更精确估算,利用山东大学威海天文台/威海市天文台的1 m反射望远镜,对7颗已知具有行星系统的恒星:TrES-1、TrES-3、XO-2、WASP-1、WASP-2、WASP-3、HAT-P-7,进行了凌星现象的观测研究.介绍观测和数据处理的基本情况,给出凌星光变曲线结果及由之推算出的一些行星参数.在总结结果并加以分析的同时,展望下一步将进行的更为深入细致的研究.

| Abstract: | By using the 1-m reflecting telescope at Weihai Observatory of Shandong University,the transit observations of seven stars are carried out to accurately estimate the physical parameters of extrasolar planets.These seven stars,including TrES-1,TrES-3, XO-2,WASP-1,WASP-2,WASP-3 and HAT-P-7,are known to have planetary systems.We will introduce the observations and data reduction,show the light curves of the transits of extrasolar planets and present some derived physical parameters.After analyzing the light cu... |
