Write down an expression for the probability of two stars in a galaxy colliding, defining any variables you use. The following table gives some values for a region in the solar neighbourhood, a globular cluster core and a region at the centre of our galaxy. Is a stellar collision likely in any of these locations? Location Stellar density Mean stellar velocity dispersion km.sec-1 pc-³ Solar 0.1 30 Neighbourhood Centre of Milky 107 200 Way Core globular 103 5 cluster
