Mass-Radius relation of Neutron Star
- I put some labels and titles in my graphs that obtained from Python code yesterday. Python is very intuitive so it’s easy to use.
# Mass vs Central density
plt.title(‘Mass vs Central density for Polytrope n = 1′)
plt.xlabel(r’Central density ($g/cm^3$)’)
- I wrote a code which calculates the Lane-Emden equation of n =1 case. This result has very similar behavior with my previous TOV solver result. I can put legends in the graph thanks to this link.
# Mass vs Radius
plt.title(‘Mass vs Radius for Polytrope n = 1′)
plt.plot(soln.t/KM, soln.y/MSOL, label=’TOV’)
- I read the paper to understand the basics of the neutron star. I think I need to read Shapiro and Teukolsky’s book first.
- I have been reading the paper to learn about the equation of state (EOS) of neutron stars.
- For future research, I need to learn C and C++ in order to use LORENE and RNS code, either of which will be used for my project.
Astronomy & Astrophysics
- I have read two Astrobites articles. I know one of the authors of the second paper. I met him in Taiwan about 4 years ago. He was very kind to students and told his story about his interests in Astrophysics and numerical simulations. During the week I had many opportunities to talk to him, and it was quite a good experience. I wish I would do good research like him in the future.
- I have added 2 new words and studied 14 English words using Anki.
- I went to the ESL class in the evening.
- I listened to the radio for 30 minutes.
