MATLAB Stellar structure equations in Matlab?

AI Thread Summary
The discussion centers around the request for a Matlab file to solve stellar structure equations, specifically to address a debate about their applicability to neutron stars. Participants express skepticism about the effectiveness of a Matlab file in resolving the argument, noting that the fundamental physics governing neutron stars differs significantly from that of conventional stars. They emphasize that the input parameters for neutron stars would require substantial modifications to the equations typically used for regular stars. Suggestions are made to reference specific academic papers that provide insights into modeling neutron stars, including the need to use the equation of state for a degenerate neutron gas. Overall, the conversation highlights the complexities involved in applying standard stellar structure equations to neutron stars and the limitations of relying solely on a Matlab file for this purpose.

Does anyone have a Matlab file for solving the stellar structure equations that they wouldn't mind passing along? I'm trying to settle an argument with a friend that they can't really be used to describe nuetron stars and I don't have much programming experience.

Thanks,

Alex

It's not clear how a Matlab file is going to settle your argument. If your friend doesn't understand how the structure of a neutron star differs from that of a conventional star, I don't think he will be swayed by the file.

I just want something that can be used to give a numerical value for a given set of conditions and see how it differs from reality.
 
How do you plan on applying the stellar structure equations to a neutron star though? It's not like a neutron star has all the same input terms as a regular star, but a different result arises due to different physics. The input terms would all (almost all) be different. If you modify the equations enough, you might as well just model a neutron star. I don't see how a MATLAB file is going to help in this case either...
 
Nevermind, forget I asked anything.
 
You can write code for a "cold" neutron star. Take a look at the paper, "Astrophysical APL - Diamonds in the Sky," hosted at http://nicmosis.as.arizona.edu:8000/PUBLICATIONS/WHITEDWARF_TOTV.pdf. Although the paper is for a "cold" white dwarf, you'll need to use the equation of state for a degenerate neutron gas instead of a degenerate electron gas. An additional paper to loock at is "Structure of neutron stars with unified equations of state" hosted at http://arxiv.org/abs/1206.6922.

Hope this helps.
