# Research

- I derived the Lane-Emden equation and considered case for the test. I’ll upload the derivation of the Lane-Emden equation during the weekend. Also, I think I can upload the solution to the problem 10-16 in Carroll & Ostlie’s Modern Astrophysics book.
- With the understanding of the Lane-Emden equation, I tried to verify my TOV solver. I looked like to yield a similar result with the analytic solution of the Lane-Emden equation, but I need to calculate the pressure profile.

# Study

- I studied 205 English words using Anki.
- I read the Nature Briefing, Astrobites, and two AAS Nova articles. I first learned about the Blue straggler and ‘living paper‘ in the AAS Nova article. I love the concept of living paper. Quite interesting.
- I asked a question about the distance squared term in the Lane-Emden equation on Physics Stack Exchange. And I got the answer.
