One of the two classes of models that have been proposed for the production of X-rays in globular clusters involves accretion of gas by a more or less massive (10 M⊙–1000 M⊙) black hole at cluster centre (Cowie, Ostriker and Stark 1978 - COS). The accretion rates are not large (~1017 g s−1), and we may enquire how such rates compare with those for accretion on cluster stars in general.
