This solver gives solutions for the following Boson Stars
| Matter type | dimension | cosmological constant | potential |
|---|---|---|---|
| Scalar Complex | arbitrary | yes | 1/2 mu^2 phi^2 |
| complex proca star with selfinteractions | 4 | no | 1/2 mu^2 A^nu A_nu + 1/4 c4 (A^nu A_nu)^2 |
The aim of this repo is that code I used for some project can maybe be reused and doesn't get lost and to spread the boson star fun. I used these papers to write this repo, please cite them since they did all of the hard work.
| Matter type | arXiv id |
|---|---|
| Scalar Complex | 0309131 |
| complex proca star with selfinteractions | 1805.09867 |
| complex proca star | 1609.01735 |
| 1508.05395 |
To install this code, run python setup.py install --user in the root directory.
For all modules available on this repo there I check consistency with constraint equations automatically with every change of the code. This doesn't guarantee that the code is bug-free, but is not completely unreasonable.
There are two scripts in the example folder, scalar_star_solver.py and complex_vector_star_selfinteracting_solver.py. They contain examples on how to use the code, especially some good guesses for the shooting that produce reasonable results.
