half_mass_relaxation_time¶
- clustertools.analysis.functions.half_mass_relaxation_time(cluster, coulomb=0.4, projected=False)[source]¶
Calculate the half-mass relaxation time (Spitzer 1987) of the cluster - Spitzer, L. 1987, Dynamical evolution of globular clusters - Need to adjust amplitude for different input units
- Parameters:
- clusterclass
StarCluster
- coulombfloat
Coulomb parameter (default: 0.4)
- projectedbool
use projected values (default: False)
- Returns:
- trhfloat
half-mass relaxation time within radius rm (in Myr)
