ASTRONOMY 157 – Stars and Galaxies - Syllabus John Perry 658-2275 (daytime); [email protected] Office hours: 1-2:15 Tue and Th, Cook 514 We will derive details only mentioned in Astr 005 with algebra and basic geometry, appropriate for non-science majors. Most class slides will be posted on UVM Blackboard. Prerequisite: Astronomy 005; Math 10 Brief Course Outline: # classes Subjects 4 Course Introduction; overview of stars with brief student presentations 2 Observing limits: effects of Rayleigh criterion and atmospheric turbulence on adaptive optics; geometric parallax; mass calculation, Cepheid distances and exoplanet detection 1 Sun: sunspots, magnetic cycle, superflares, coronal holes 1 Molecular clouds and the Jeans mass limit for collapse; Fragmentation; protostar observation limitations 1 Early collapse stages: expanding photosphere; stellar modeling equations; effects of rotation, mag. Fields, collisions etc. 1 Nuclear fusion cycles, total energy production, star lifetime estimation; photon random walk calculation 2 Core collapse, H shell burning, expansion to red giant, helium flash, heavy element production 1 Planetary nebulae, supernovae and gamma ray bursts 1 White dwarves: surface gravity, derivations of degenerate gas pressure, radius/mass, density, mass limit and visible lifetime 1 Dwarf binaries, mass transfer, type 1A supernovae; dark energy 1 Neutron stars: derivations of radius and density; pulsars; binary pulsars and tests of general relativity 1 Stellar black holes; details of Cygnus X-1; mass/radius derivation 1 Galactic BH’s; Milky Way and M87 core radius and mass derivations; various arguments for BH’s 2 Overview of nearby galaxies and galaxy clusters; standard candles 2 Galaxy and cluster formation, galaxy evolution, stellar populations 2 Galactic mass distributions, derivation of galactic rotation curves, comparison to observations; dark matter distribution, MACHOS 1 Spiral pattern and material rotations, shock formation, star birth triggers and inter-arm travel time 1 Quasars; galactic BH formation; Lyman alpha forest Recommended Text: Web references Grade Structure: Midterms (2) - 30% each Final exam - 40% Exam Format: Eight to twelve questions will be posted on Bb several weeks before each test. Two of them will appear on the test. Each question will have five parts, two of which are posted and 3 of which are not, but pertain to the same general subject. There is no homework beyond preparing answers for these questions.
