... Following Sivakoff et al. (2007), the stellar encounter rate can be written as M 1.5 GC r -2.5 h , where MGC and rh are the GC mass and the half-mass radius. ...

... The individual channels are nominally 8 1 pm diameter (yielding an 80 : 1 LID ratio) arranged in a hexagonal close-packed structure with 10 1 pm (typically 9.5m) channel-to-channel spacing. ...
... Taking the mass-loss rate from Faber & Gallagher (1976), we estimate the accumulated mass from stellar mass loss over the Hubble time to be 1:5 ; 1010 M , which is comparable to the total mass of the hot gas in the core-tail structure (2 ; 1010 M ). ...
