Using basic principles from previous Physics modules such as thermodynamics and quantum mechanics, we will show how basic properties of stars can be inferred and compared to observations using static stellar structure models. We will discuss energy generation and transport mechanisms, and describe the interplay of  important physical processes such as mass loss and rotation. We will learn how the initial mass of the star influences its evolutionary pathway and final fate (white dwarf, neutron star, black hole). Although the bulk of the module will focus on single star evolution, we will show how the presence of a nearby companion can profoundly affect the evolution.","valueSv":""}},{"title":{"valueFi":"Suoritustavat","valueEn":"Study methods","valueSv":""},"content":{"valueFi":"","valueEn":"Participation in classroom work  \r\nWritten exam\r\nMinimum 50% of exercises, 50% of computer tasks, and the final exam.","valueSv":""}},{"title":{"valueFi":"Toteutustavat","valueEn":"Course unit methods","valueSv":""},"content":{"valueFi":"","valueEn":"Lectures: 18\r\nExercises: 5 (sessions)","valueSv":""}},{"title":{"valueFi":"Oppimateriaalit","valueEn":"Learning material","valueSv":""},"content":{"valueFi":"","valueEn":"Combination of lecture notes, articles, text books.","valueSv":""}},{"title":{"valueFi":"Lisätiedot","valueEn":"Further information","valueSv":""},"content":{"valueFi":"","valueEn":"Offered in even numbered years during Autumn.","valueSv":""}},{"title":{"valueFi":"Kurssikirjallisuus","valueEn":"Literature","valueSv":""},"content":{"valueFi":"1.
