Description Two questions with problems solving and two of laws explanations (Newtons and Keple'rs), for the thirds question there is an example that has to be provided and on the fourth one besides the laws, two other scientists that contributed on this theory
Description Has to be done well. All of the items tagged bellow are the topics that will be covered on the test. Please let me know if you have any questions bellow I am willing to answer.
Description Please read the information before taking the offer and if you cannot do it than do not take the offer. This is a very important labs See the the papers below
Description Submit all graphs in Excel or similar form. (a) (1) Show explicitly that for very massive stars (opacity dominated by Thompson scattering, pressure from radiation) that luminosity is proportional to mass. (2) Show explicitly that for moderately massive stars (opacity dominated by Thompson scattering, pressure from gas) that luminosity is proportional to mass cubed. (3) Testing the predictions of the stellar structure equations. Here "LuminosityMass-data-Kuiper.txt" ATTACHED BELOW you can find a file containing data on the luminosity, mass and radius of a number of stars measured in visual or spectroscopic binaries. The data comes from a seminal paper "The Empirical Mass-Luminosity Relation" by Gerard Kuiper (of Kuiper belt fame), which you can find here. Plot: (i) Log L/Lsun vs Log M/Msun. Does it agree with the various mass-luminosity relations in the appropriate mass ranges? (ii) log(R/Rsun) vs Log M/Msun. Does it agree with the various mass-radius relationships in the appropriate mass ranges? (b) Distances and ages using the HR diagram (1) Plot the Pleiades' absolute magnitude vs B-V on the same graph as the apparent magnitude vs B-V of you third (non-Pleiades and non-Hyades) cluster. By matching their main sequences, determine the distance to the third cluster. (2) See the HR diagram of the M5 globular cluster below. Estimate its age. (c) (1) Set up and collect the results of simulations of the structure and evolution of a 1,2,5,10 and 20 solar mass star in MESA(Click to go to the MESA website). We will look at these next week. (2) Find some piece of physics that you recognize (or don't recognize but look up) in the MESA paper, and post about it in the MESA discussion thread (there will be one MESA discussion thread this week and the next; you need to post in one of them.) YOU CAN USE VIDEO TUTORIALS BELOW: 1- 2- 3-

Description 1) A sudden increase in the energy generation rate in the core of a star results in a sudden increase in internal pressure. Use the virial theorem to argue that the star will remain stable (i.e. use the virial theorem to figure out the sequence of changes that will result from the sudden increase in pressure.) 2) Question 15.4 from "Foundations of Astrophysics" (see attached picture) 3) Question 15.7 from "Foundations of Astrophysics" (see attached picture) 4) Question 15.8 from "Foundations of Astrophysics" (see attached picture) 5) Use the figure below to estimate the mass of a star which generates 90% of its energy using the CNO cycle. (see attached graph)
