Challenge 1
Equal mass cluster in isolation and in a tidal field
PI: Alice Zocchi
Other active participants: Mark Gieles, Vincent Henault-Brunet, Anna Lisa Varri, Antonio Sollima
Questions to address:
- What is a suitable model to describe post-collapse clusters? We here consider 3 models:
- Isotropic King (1966)
- Anisotropic Michie King
- How much does tangential anisotropy/retrograde rotation due to the tides matter?
The relevant snapshots from simulations of an isolated cluster and cluster within a tidal field are available in section A of the Mock data page.
Comparison $f_\nu$ and isolated models
MCMC fit results to tidally limited models
Isotropic lowered isothermal models
Example comparison between the 3 best-fit isotropic lowered isothermal spheres at different times:
Anisotropic lowered isothermal models
Preliminary results for a Michie-style anisotropy fit:
