高爽，河马老师
I am an astronomer, a teacher and a scientific writer at Department of Astronomy, Beijing Normal University
When I was a very young boy, I sat in a dome at Beijing Planetarium and enjoyed the dark. Astronomy, to me, is science and more. It reveals something beyond our imaginations and discovery new worlds. Besides, astronomy is beautiful and amazing to share with everyone. I would like to investigate, teach, present and talk with you about the world that can be understood from our pale blue dot.
Now I work at DoA, BNU as a lecturer. I am working on the study of Galactic stucture, stellar binarity, and something new based on spectral survey data. Also, I publish articles and make mini videos for public outreach. I give a new lesson History of Astronomy at BNU.

Usually some web-based models need to be submitted many times to collect full dataset. A python code has been developped for this application.
We estimate the fraction of F,G,K stars with close binary companions by analysing multi-epoch stellar spectra from the Sloan Digital Sky Survey (SDSS) and LAMOST for radial velocity variations. We employ a Bayesian method to infer the maximum likelihood of the fraction of binary stars with orbital periods of 1000 days or shorter, assuming a simple model distribution for a binary population with circular orbits. The metal-rich stars from our sample are therefore substantially less likely to possess a close binary companion than otherwise similar stars drawn from metal-poor populations. The different ages and formation environments of the Milky Way’s thin disk, thick disk, and halo may contribute to explaining these observations. Alternatively, metallicity may have a significant effect on the formation and/or evolution of binary stars.

在课堂教学活动中，情感的重要程度远远大于方法，远远大于知识。
课堂内容必须有故事，故事必须有情感。
利用故事和情感首先点燃自己，释放的温度可以影响学生。

在天文学史课上，河马老师引领我们神交先贤， 叩问苍穹。星辰如此夜，风露立中宵。
在我大一的上半年的全部课程里，河马老师的天文学史是我收获最大的。在这里你真的有学习的感觉，思考，交流，批判，仿佛真的置身古希腊“浴室”或文艺复兴时期的欧洲大学。享受着探索人类真理的过程！
