Look at my cat!

I am Yiru Chen, from Benxi, a beautiful small town in Liaoning Province, China. I am now a master's student in the Department of Astronomy at Leiden University. In my spare time, I enjoy feeding myself and my cat.

As more and more astronomical data are accumulated, verifying the effectiveness of existing mathematical models and improving existing mathematical models are issues that need to be faced in future astronomical research. If you are interested in the method, please feel free to discuss it with me.
