Summerstudent project

Git for summerstudent project on evolution of open cluster (see project description)

A manual to run the code and get output in correct format is present: nbody6_quick_guide.md.

TODO list:

Practicalities

• Get nbody6 working and get to know the code
  • Make appointment with max and go through things
• Make it fairly easy for the student to work with nbody6
  • make output scripts
  • Create environment to run things on. i.e. go to IT
• Ask someone to send us a couple of review papers on clusters
• Write up a more solid form of the project description
• Stay in contact with Mark and Fabio, keep them in the loop of any further advice. Also discuss with them semi regularly about the topic.
• Create quickstart manual for us
• Try out mcluster for the setup of Nbody simulation settings. They have a nice manual
• Fix script for mcluster to put everything in a nice place with the logs
• Finish the python config generator.

Scientific

• Decide upon the following scientific things:
  • Total mass: What range of cluster masses/Total number of stars will we decide to evolve?
  • Density profile: What will be the density profile that is the most sensible? See paper of Douglas and Heggie for inspiration
  • Tidal field: Vary between no tidal field and tidal field? Think about this
  • Binary fraction: Binary fraction for stars, and will we do a uniform one or mass dependant?
  • Eccentricity distribution: Thermal is fine, but flat is also okay i think.
  • Period distribution: Sana 2012 if possible.
  • Initial mass function: Lets decide to start by using the standard kroupa for now, no reason to do so otherwise, however choosing single mass is maybe good as a reference to other work.
    • Mass limits: Decide which mass limits to take. Is 100 solarmass enough?
  • Mass Segregation: I think no initial segregation, because we want to see, with an initial cluster, how the segregation occurs. But i am not sure if forming clusters have any segregation at all?
  • Fractality: This is to simulate the imperfectness of the spatial distribution of stars at formation. I wonder how this can affect the outcomes.
  • Stellar evolution settings:
    • Use pre-evolved setting with cluster, might be fun to test out the paper via a shortcut
