Dust in the core of the metal-rich globular cluster NGC 6356

We report the 3.5 sigma detection of dust in the core of the metal-rich ([F e/H] = -0.4) globular cluster NGC 6356, The dust mass in the core is simila r to 4-17 x 10(-3) M., depending on the dust equilibrium temperature. We ru le out sputtering as a grain destruction mechanism in NGC 6356, unless grai ns are very small (similar to 30 Angstrom), We also place the upper limit o f 6.6 x 10(-3) on the CO-to-dust ratio in this cluster. This value is signi ficantly smaller than the CO-to-dust ratio in the general Galactic interste llar medium, and in the outflows of evolved stars.
