 # Summer project: Black hole retention in star clusters:
 ## Description:
-Black holes in clusters of stars play a significant role in the evolution of these clusters and depending on how many there are at the start of the evolution of the cluster, the cluster may evolve to end up with as little as 0% of its mass fraction composed of black holes or up to nearly 100% of its mass fraction composed of black holes. This in turn has implications for the possibility of intermediate black holes and further cluster evolution.

 How many black holes there are at the early stages of the cluster evolution, also called black hole retention fraction, depends on several factors, among which are the cluster properties (e.g.: initial density and mass) and stellar evolution (e.g.: initial-final mass relation for black holes, kick distributions). Our plan is to to use some cluster evolution models to probe how sensitive the outcome is to certain parameter variations like the kick distributions of black holes.

 ## Period:
-Start of july - End of August (exact dates YTBD)
+1 july - End of August (exact dates YTBD)
 
 ## Week to week plan:
 ### week 1:
+- [ ] Reading into Globular clusters and Open/Young clusters
+- [ ] Reading into stellar evolution
+- [ ] Get familiar in the group
+
 ### week 2:
+- [ ] Get more into stellar evolution
+- [ ] Read into stellar formation
+- [ ] Get familiar with concepts like initial mass function, black hole formation
+- [ ] Calculate 'goldilock zone' for cluster (calculating escape velocity based on cluster parameters to see which parameters allow for escaping of black holes)
+- [ ] Calculate, using the IMF and a range of masses, how many black holes will form in a cluster of a given mass.
+
 ### week 3:
+- [ ] Using the results of last week, decide on initial conditions of the cluster that we will evolve.
+- [ ] Read a bit about the N-Body6/7 code 
+- [ ] Set up some initial simulations and get the output
+
 ### week 4:
+- [ ] Do simulation of some clusters
+- [ ] Start with analysing results of the first simulations 
+- [ ] Make some scripts to analyse the data, try to interpret it and understand it
+
 ### week 5:
+- [ ] Run some higher resolution simulations
+- [ ] Possibly set up a very big simulation
+- [ ] Analyse the results
+
 ### week 6:
+- [ ] Decide whether to do more simulations
+- [ ] Modify some physics and try out some hacks  (e.g. putting some initial black holes in the cluster)
+
 ### week 7:
+This is coming to the end but its also quite far away, so the goals here are a bit general
+- [ ] Analyse data from calculations
+- [ ] Write up results and write up a form of report 
+
 ### week 8:
+- [ ] Same as week 7
