increasechief/chromastar: Pedagogical Stellar Atmposhere and Spectrum Modelling of Stars

Compute the vertial structure of a static, plane-parallel, one-dimensional stellar atmosphere in local thermodynamic equilibrium (LTE), and to compute the emergent spectrum incorporating opacity computed with a comprehensive atomic line list from the NIST Atomic Spectra Database ( (Kramida, A., Ralchenko, Y., and Reader, J., and the NIST team, NIST Atomic Spectra Database ver 5.3, National Institute of Standards and Technology, Gaithersburg, Md.). Provides post-processes data products that are ready to visualize in an R IDE such as Shiny. Useful for senior undergraduates in astronomy and physics to experiment with and develop a stellar astrophysical modelling code in a graphical IDE, and to compare observational data to ad hoc model output. This is a port of the Python ChromaStarPy code ( and will be kept updated to that.
