A first course on stellar interiors and atmospheres in which approximately 50 percent of a semester is devoted to each. Stellar Interiors topics cover hydrostatic equilibrium, the Virial theorem, energy generation and transport, overview of stellar evolution, PMS Evolution, main sequence evolution, late evolution, evolution in close binary systems, stellar modelling (in part), the approach to real models. Stellar Atmospheres topics cover basic Radiative Transphere, transport Equation, Eddington-Barbier approximation, line and continuum transfer in LTE, radiative transfer in static Plane-Parallel stars. exponential integrals and the Schwarzshild-Milne equations, Lambda, Phi and Chi operators, various Eddington approximations, Atmospheres of Static Plane-Parallel Stars, pressure stratification, temperature stratification, radiative equilibrium, Gray-atmosphere approximation, spectra from static Plane-Parallel stars. line broadening mechanisms, spectral line formation. See A450 & A553 for full-fledged courses.

In this course we study the Galactic interstellar medium, the processes of star formation, and the interaction of stars with their birthplaces. We will heavily emphasize phenomenology and modelling of observations – rather than observing techniques and fluid-mechanical theory. The main effort of each student will be exerted in a term project, in which they will learn to use standard software packages to model sets of observations of interstellar gaseous objects. The class is aimed at first- and second-year graduate students in physics and astronomy.
