This will be a reading course in Advanced Stellar Astrophysics, with weekly readings covering the basic physics that goes into stellar models and modern applications in astronomy, and weekly numerical exercises using the MESA stellar evolution code.
Prof. Andrew Cumming, Rutherford Physics Building 310, email andrew.cumming-at-mcgill.ca
You should have taken PHYS 521 Astrophysics or an equivalent upper-level undergraduate course in astrophysics.
Before the first meeting of the course, you should have installed MESA following the instructions here, and ran the example of single star evolution described here.
Wednesday and Friday 9-10.30am, MSI conference room. First meeting will be on Wednesday Sep 14. See below for the detailed schedule.
How stellar models are constructed and evolved
Physics input in stellar models:
Asteroseismology (stability and pulsations)
Stellar evolution:
We will divide into groups of two. Each week, one group will present a short summary of the highlights/important points from the reading, covering both the basic physics ideas and current open issues/questions in the field (Wednesday class). Another group will devise a numerical exercise using MESA for the rest of the class to try out (Friday).
