PHY 521: Stars Stellar Evolution Overview We will go through the qualitative aspects of stellar evolution, following Ch. “An Introduction to the Theory of Stellar Structure and Evolution”, (2nd ed) Cambridge University Press, ISBN 0-521-65937-X 3. We'll defer the sections about explosions and close binaries until later After this, we'll spend the next few weeks building up the physical ideas needed to integrate the equations of stellar structure The heavier elements did not yet exist. 5 ⋅ Theory of Stellar Evolution first integral of the equations of motion yields (5.2.10) or v ∝ r (5.2.11) This says that at any time the velocity of collapse is proportional to the radial coordinate. A. Maeder, 2009 (M) (recommended if you work in stellar modelling and evolution: very thorough) “Physics, Formation and Evolution of Rotating Stars” … • We study stellar properties, and use our knowledge of physics to construct models and draw conclusions about Observing Stellar Evolution Metals – This is an odd term, but astronomers talk about the chemical elements that comprise a star. Stellar Evolution. Units of Chapter 12 Leaving the Main Sequence Evolution of a Sun-like Star The Death of a Low-Mass Star Evolution of Stars More Massive than the Sun Supernova Explosions Observing Stellar Evolution in Star Clusters The Cycle of Stellar Evolution. courses on stellar astrophysics (e.g. 2 of your text closely. in PDF format Request a copy of the Stellar Evolution poster When the Universe came into existence ~14 billion years ago, the only elements were hydrogen, helium, and traces of lithium, beryllium, and boron. Stellar Evolution • Astronomers study stars in much the same way • Stars come in many varieties, and change over times much longer than a human lifetime (with some spectacular exceptions!) Any element heavier (in the atomic sense) than helium is called a 'metal', even though this does not match our day-to-day use of the word. This is a self-similar velocity law like the Hubble law for the expansion the Utrecht first-year course Introduction to stellar structure and evolution by F. Verbunt). Stellar Evolution is a magnificently written book and will serve for a long time as a source book for astrophysicists working on related problems. The book is very nicely edited with three indices: one for authors, the second for subject and the third for the stars is the one which will be appreciated most by the worker in the field. The goal of this course on stellar evolution can be formulated as follows: to understand the structure and evolution of stars, and their observational properties, using known laws of … • How do we know they evolve?
