AST 390: Computational Astrophysics#
This is a collection of notebooks on computational (astro)physics. Starting at the beginning, these notebooks introduce numerical methods for derivatives, integration, rooting finding, ODEs, and linear algebra and then move onto applications in astrophysics.
List of Astrophysical Applications#
An example of integrating to infinity by integrating the Planck function over wavelength.
Combining integration over the Fermi-Dirac distribution and root-finding to find the electron degeneracy parameters.
Shooting methods for two-point boundary value problelms applied to the Lane-Emden equation for polytropes.
Lorenz System Stationary States
A demonstration of using Newton’s method to find the stationary states of the Lorenz system.
