For this assignment you should use some stellar evolution code to simulate a set of stars evolving from pre-main sequence to the end of their life. i recommend using mesa for this, it can be run directly from a web gui on the mesa web. you can also the source and install it your self. the mesa marketplace has a dockerized version of mesa. mesa web (links to an external site.)links to an external site. mesa star source (links to an external site.)links to an external site. mesa marketplace (links to an external site.)links to an external site. if mesa gives you trouble, or seems a bit too much, you can try the ez "mad star" code instead, it also runs through a gui to a web server. mad star - ez-web (links to an external site.)links to an external site. you ought to run at least 9 stellar evolution models.
1) set up a model for the sun. run it and plot the output to show the trajectory of the star in the temperature/luminosity plane. then pick two models which have the same mass, but significantly different metallicities than the sun. run and plot those models, and compare with that of the standard solar model. comment.
2) now pick a different mass star, and run it for solar metallicity, and at least two more different metallicities at the same mass. do the same plots and comment.
3) pick another mass - making one mass higher than solar mass, and the other lower than a solar mass. again run the model for solar metallicity and pick two different metallicities to run and compare. as before plot and compare. discuss.
