Galactic kinematics and structure defined by open clusters
《Research in Astronomy and Astrophysics》2009年第12期1285-1302,共18页Zi Zhu 
funded by the National Natural Science Foundation of China (NSFC) (Grant No.10673005)
On the basis of recently published astrophysical parameters of the open clusters, we have selected 301 clusters with measurements of their kinematical parameters to trace the local structure and kinematics of the Gala...

The Cepheid PL zero-point based on the revised Hipparcos trigonometrical parallaxes
《Chinese Science Bulletin》2009年第20期3790-3794,共5页ZHANG Hong ZHU Zi 
Supported by the National Natural Science Foundation of China (Grant No. 10673005);Foundation of the Chinese Academy of Sciences (Grant No. KJCX2-YW-T13)
Revised Hipparcos data were released by van Leeuwen in 2007.In this article revised Hipparcos trigo-nometrical parallaxes are used to derive a period-luminosity zero-point in the optical V band.Adopting a fixed slope ...

利用新编依巴谷天体测量资料研究银河系运动
《天文学报》2009年第2期213-223,共11页沈鸣 张鸿 
国家自然科学基金(10673005)资助项目
根据最近发表的新编依巴谷星表数据,重新研究了经典造父变星周光关系零点问题.利用运动学模型对自行数据和视向速度分别拟合奥尔特常数及本地静止标准的旋转速度,得到太阳的银心距R_0=8.0±0.8kpc.从太阳附近的旋转曲线,发现银河系盘的...

Revisiting the Local Kinematics of the Milky Way using the New Hipparcos Data
《Chinese Journal of Astronomy and Astrophysics》2008年第6期714-722,共9页Fang-Ting Yuan Zi Zhu Da-Li Kong 
supported by the National Natural Science Foundation of China (grantNos. 10333050 and 10673005).
With the new Hipparcos data recently released, we reexamine the kinematics in the solar neighborhood. Two different populations of objects, namely the thin-disk O-B5 stars and the thick-disk K-M giants, are selected f...
